Do you use these to gig with? because if you do, your gonna need the whole stage to set this puppy up! the sizes12-13" concert tom, then descending to the regular two headed tom 12"-13"-14" you'll have to tune the concert toms very high! since your duplicating sizes, but it will work, and you can set them up in any order that strikes your fancy no set in stone rules here!

Other than purely aesthetics, it matters not one bit. But as vm2k says, tuning will be the key to consistent sound. As you do the Peart run up and down, you want to have them in order of descending tone. I would think they will look nicer in order, but if you don't need every little note, then why bother? On the point of being able to pick up both toms, I would for the future utility of it. You may not always play high-voltage and may find the need for the other tom, and having a full run-up will make some kid in 30 years very happy! If it is not a bank-breaking deal, I would grab both of them.

With all those drums, you need another bass.

Yeah, I don;t gig with them, they are my museum set LOL! I can see the point of buying them both if down the road I pick up another bass, if not, maybe I should just get one of them, I would have concert toms in 10/12/13 then start with my reg 13 tom..........hmmmmmmmmm decisions decisions,

The only time that something like this would matter would be in a situation of presenting something in a setting of historical accuracy. Vintage drums have a somewhat "traditional" setup and look. And sometimes, the hardware and badge placement can be an indication of what the intended "display" was, in general. But, in application, there are no set rules as to how the drums should be placed.

If it were me, I'd set up the full toms in descending order as if to play. I would then position the single headed in the left and right gaps. I'd go high pitch on the right where the deep full toms are and the larger single heads on the left where the higher pitched full toms reside. That would maximize the tonal range on either side. But that's just my take.

I'd hire a roadie............

I used to play a large rogers set with 3 8x12's that took all the guess work out just tune em how you want em and put em where you want them it is amazing the combos of tones you can come up with have fun and yes get that other bass a 14 by 22 or 20 and you will be on your way to solo heaven.. have fun
