The CB is definitely forward of center, as your center of mass when seated with your legs out in front of you isn't right under your hips, but a little forward as well. You don't really want to be leaning on the coaming - you want to be able to bend backwards a bit if needed. Many 'yaks definitely have the back band close to the coaming, but I'd still put it at least an inch forward of the coaming edge.

MHO, of course, it's your boat. Set it in the water before you put in the seat, and have someone take side on pics while you move a bit in the cockpit to see where the boat best balances out.
