I have played with various different setups, but always end up back in this configuration as I seem to find it most comfortable.
I started out playing on the standard 5piece setup with the two toms mounted off the bass drum, quite high up, therefore crazy angles, but the more I played and adjusted things the more it all settled down, lowered and flattened out.
Give it a try, change anything to anywhere, and see where you are most comfortable with it, get ideas from other kits, experiment and have fun.
