In terms of space saved you're absolutely right. There is virtually no difference if depth is equal. I happen to like 18 and 20 inch bass drums (for stated tom height) but fully acknowledge it's not taking up less space. They're a bit more portable and fit in the car easier maybe but even that...
It's amazing how we all have different ears. I love my CCJ. The toms sing and the bass drum punches. I use it often. I also have a Brooklyn so it's not like I'm Gretsch ignorant.
Those center lug Catalina Clubs came out in the early 2000's and were replaced by the small single sided lugs by mid...
IMO when it comes to portability/sound, shallow drums with larger diameters will win every time over small drums like the Breakbeats, Midtown, etc. I'd much rather play a shallow 20" than a 16"x14". The pitch will be lower and it'll take up less space. Win/win.
The Tama or Taye Go kits linked...
Those are Catalina Club Mods. The bass drum is 20" deep BTW which would be a sticking point for me but that may not be an issue for you. 350 would be a good target, yes.
I have a Cat Jazz and love the sound and light weight.
I always assumed they got Ringo because they liked the way he played. Some people just don't make the cut. It happens all the time. Also they didn't know they were going to be the biggest band in the world of all time which makes it seem even more tragic for Best in hindsight.
I use a number system with a Sharpie on the back of the memory locks but the kit that has them doesn't get much action these days. I can usually get my floor tom set up right pretty quickly without them.
Pretty close-minded post there but it's your business if you don't want to learn anything new. For the rest of us it's the furthest thing from selling out.
And from all of us out there who have had to do "undignified" work to make ends meet...your contempt for working people is duly noted.
