Hi.
Just are as far as kit configuration goes. I was never a massive fan of the 12,13 mounted toms with the 16FT. Its alright I suppose but I find the 10, 12 sizes make it a little easier to navigate around the kit. My main setup has been just a standard four piece but I've also been through a stage where I add an extra floor tom, one up two down arrangement. I've also had 3 up 1 down, and 2 up 2 down but with the toms off to the side of the bass drum- kind of like a four piece position but with the smaller tom over towards the hihat. I find if the toms go to far to right in my case as a right handed setup, where the 13" sits traditionally, then its not as comfortable. Probably because it starts moving the ride further away.
Whatever the setup I eventually adapt I suppose, but some I find better for certain situations than others.
Anyway, I'd be interested to hear what others philosophies on drum setups are.
