Any chance you can try out the various length risers before buying. There's a pretty big difference in the feel between an A and B riser, IMO.
The B riser, no. 2 limb combination will give you a 62-inch bow. However, given your draw length, a 60-inch bow (A riser, no.3 limbs) would provide more than enough length. On the other hand, if you really want a longer bow, go for it.
Not as many older no.2 limbs available as there are no.1s or no.3s, but Bear did just start making no. 2 limbs again.
