Having that stuff due to your physical condition is cool then. I wasn’t aware. Rock on!What I took off was the 12" rack tom, and one cymbal stand and one china cymbal. Having ANYTHING less to carry makes a difference for me; my hardware bag is lighter without that one extra cymbal stand, and the double pedal is in a separate bag. But you're right, the number of trips is the same with out without those things. The biggest difference was the ergonomics of the kit, for me.
You mentioned losing the double pedal and not needing one. I used to have a single bass drum pedal. I don't have a double pedal just for the sake of blasting out 16th note licks (although I will indulge in that at the end of certain songs, and the audience and band like it). I know I've had some posts about this a while back, but for me, the double pedal and second closed hi-hat are needed, but my situation is FAR from normal. I sustained catastrophic injuries in 2009 leaving me with a severely damaged left (hi-hat) leg, and losing my right (bass drum) leg below the knee. I had to re-learn how to play the bass drum, basically using a combination of my right leg (with a prosthetic), and my left (with little to no ankle movement). What I came up with is to play the bass drum with my prosthetic right leg, OR my left leg using the slave pedal, OR both legs for certain combinations. When using the left leg, I use my second closed hi-hat so I get a tight closed hi-hat sound. I have played and can play entire songs/sets solely with my left leg on the slave bass drum pedal if needed. Certain figures REQUIRE both pedals. I have to play "heel up" on both sides. Certain bass drum licks such as "Walk this Way" require me to use both feet. Certain licks like the intro to "American Band", or certain sections of "Separate Ways" require both feet for me. Or even just a two 32nd notes require two feet. (Before the injuries I could of course play most of these things with one foot). And hey, since I now have a double pedal why not throw in some double bass stuff here and there. Such as the infamous tom/tom/bass drum/bass drum lick done as 16th/32nd notes as the end of songs on a sustained ending, say on "Jump" or something. I've been amazed at the mileage I get out of that old lick from the audiences.
I've thought about doing what you've done...a really stripped down set. But I'm already carrying a cymbal bag anyway, and 16/18/20 is my current minimum. For a while I was going without a ride, but a bass player asked me why the hell I didn't have a ride, for when we were doing "Uptown Funk" for the ride cymbal/bell section towards the end.
Thanks for the ideas and input.
