Okay, I currently have : -
1) Sonor S-Class Pro, Birdseye finish, 20, 20, 8, 10, 12, 14.. but no 16 despite trying to find one for years.. I rescued this from a barn a few years back, lovely kit. Having 2 kicks is handy (I never set them both up).
2) Premier Signia in Rosewood finish. This was my dream kit when I was a kid in the 90's. I actually went a bit mad and ended up buying 2 sets 2nd hand (during the last few years) so I could get the 20" bass drum and the 8" tom. I now have these shells: 22, 20, 16, 14, 14, 12, 12, 10, 10, 8... So I need to sell a few shells I think ;-) I still love the Signia, but I do wonder if it'd be my first choice now. Sometimes it's good to move on. It sounds great, but I can't get spare parts, the badges have gone funny, the bass drum has a funny sized down tube holder so I can't get a better tom mount (I hang off cymbal stands these days, the Premier mount is shockingly bad).
3) Premier XPK, 1996.. this was my first real kit (which I still have stored in my garage). Officially my first kit was a red Hohner.. I remember putting my foot through the kick pedal! It was cheaply made..
4) Mapex Saturn III, Red Supernova Burst (20, 20, 16, 14, 12, 10, 8).. which I have for sale. It's a lovely kit, but I just don't need it.
5) Lots of Paiste Signature cymbals, and a Sabian 10" splash.
6) Yamaha DTX 750 electric kit.. which hardly gets touched now I have my little studio with the Signias in.
Now, if all of that was to disappear and I had a load of cash in my hand... I'd probably pick up a Sonor Ascent / Select Force brand new with the finish / sizes I wanted. I'd get 6 peices (1 snare, 1 kick, 2 rack, 2 floor) 20, 16, 14, 12, 10.. (though most of the time I'd play 1 up and 1 or 2 down).
I would probably go Paiste again, but perhaps look at their darker cymbals (I currently have mostly Signatures), or at least have a broader range, rather than lots that sound similar. I'd also get more effect cymbals. I've been thinking of picking up a 18 and/or 16 Meinl Vintage Trash Crash recently..
I sometimes wonder about selling up *everything* and starting again. It'd be exciting. I doubt I'd sell the XPK as I have nostalgia for it.
Playing wise, if I was to start again, I'd have spent my younger years practicing a lot more, or at least practicing *properly* a lot more, and found a really reputable teacher or 2 to help me.
