If you don't mind me saying so here, I think the idea of the two off-set toms is flawed. And the number one reason is because it causes you to push your hi-hat a little farther out of the way than would be comfortable, just so you can have a drum in there that you'll only use maybe 15% of the time. And you'll be using your hi-hat at least 90% of the time.
So the idea is to have the instruments you'll be using more, in a comfortable spot. And then everything else follows around those. So, bass drum, snare drum, hi-hat, and ride cymbal, need to be where they are comfortable for you.
Your feet and legs shouldn't have to be doing anything strange to be on the pedals. Sitting on your throne shouldn't be too different from how you would sit correctly in a chair, or on a stool. Once you accomplish the proper placement of those four pieces, everything falls in around those, and you will be in ergonomic nirvana.
I very often play with tom on a separate stand, I've done so since the 90's. I have to disagree with you assertion ; it doesn't push the hihat farther at all.
At least as long as you use a twin pedal.
I played this with 12 and 13 (or 10 and 12), I push the stand the closer as possible to the bass drum, and really, it brings the 13 closer to the center of the BD than the 12" would be on a bass mount.
The thing it does is bringing the ride closer and placing the 12" right under the crash.
The first time I done so, it was to replicate the twin BD placement and it worked really well.
Jeremy "Bean" Clemons has an interesting set-up.And he play's it here ... https://www.youtube.com/watch?v=1dSKx7_4nbM
If you look at Tamefx's setup he has offset toms, BUT everything is tight because his tom level is sitting higher than yours, and more tilt, thats why he could tighten them in. His far tom is essentially at or above the level of the high hat, whereas your early pic was not. You see many drummers doing this who have toms off to the left, as they have to go up higher (see the drummer from Phish in pic).
By all means try anything, thats why equipment comes with all these options. Just for stability though, if you have a bass drum mount, didi you try to get your 12 hanging centered over the BD on that. That would free up your stand the 10 is hanging on.
Please get a 4x8 rug and put it under your rig. Once you get it setup nice and comfy you can use tape to mark off the layout and have a reference for when you need to move your gear. Plus the kit won’t run away from you. Videoder Tubemate Snaptube
You are on the right track to though. Please don’t worry about keeping your toms flat. Mount them back on your bass drum and angle them 30ish degrees or so. Now you can lower them to a comfortable height and strike them with efficiently without hitting the rims - unless of course you want to!
You are going to want to move your floor tom leg away from your bass drum pedal.
Ps, I’m 5’7” so not much difference.....
Using one up one down would work, and so would one up two down. Peace and goodwill.
I'm 5'7 and was always trying to get my toms as low as possible, and flat. Even bought a 20in bass drum to facilitate this, but I found I was always reaching (even if only a little) for my toms which, after a bit of playing, would cause pain in my lower back. Then I stumbled on a video by Bob Gatzen where he talks about bringing the drums to you, so you are not reaching. Dave Weckle also mentions how before he sets up his toms he air drums a fill without moving his back, and that is where you want the toms to be. I followed these two principles, my toms have come up and angled (so that when your stick hits the head they are almost parallel to each other) and I now play a 24in bass drum with room to spare between it and the 12in tom, and the back pain has disappeared.
Yes, my toms are as high and angled as if they were on a bass mount. The tom Tripod is as close as it can be to the bass drum. My snare and Hihat are at the exact same position as if I was playing the toms over the bass drum (I play indifferently both set ups.)
I do so for two reasons : having the biggest tom in front of me. And to bring the ride closer.
The pic below was with 12 13 16 setup - with cymbals too high !!! The SD and the hihat are in the normal position, the only thing I moved from the normal position was the cowbell.
I'm not very tall either (1,71 mètre ; 5,6 ft), I don't understand all the trouble the OP goes through ; I played power toms over 22" almost all my drumming life.
Dragonfly 66, you're making things too complicated, I think. I don't see the use of a specific pedal (the vector). When you play concert, backline kit you don't have the time to adjust everything, you need to adapt quickly. Your kit is bloody nice, with a 20" bass and shallow toms, a good start.
During the 80's 90's people not taller than you could play power toms over 22 or 24 BD. This wasn't ideal but they manage.
Try to bring your Tom stand closer to the bass drum so that the lower rim is just over the highest part of the bass shell, and angle the toms. Flat toms are fashionable but it's not for everyone.
Looking from the picture you sent :
Joking aside but get a carpet - bloody nice kit with great cymbals.
Everything seems "on" the drummer : floor tom is too close, the crashes are too low, you can't have power if they're that low. The racks are way too low, they're below your hats, and too much off-set.
In the event that you take a gander at Tamefx's setup... on the off chance that you have a bass drum mount, didi you endeavor to get your 12 balancing focused over the BD on that. That would free up your stand the 10 is holding tight.
So using the bass drum mount for the 12" does allow me to get back to my natural stance with just a tad bit of the 10" drum covered. This feels so much better to me. The 10" can only go so high before it hit the hi-hats. The 12" can only go so low before hitting the bass drum. So the 10" and 12" are not at the same height, which seems awkward. The only way to remedy this is to push the hi-hat back out so the 10" can be lifted. The 12" cannot go any lower on the bass drum mount. This puts me back to the wider stance when both toms were on the dedicated mount.
I think there is just no getting around the fact that there must be a wider stance when the toms are off set. I just have to play with the wider stance and see if I can get used to it.
