I just bought a new set of no 2 limbs. I do have a B riser, but I bought them to use on my A riser. If this set is any indication, Bear seems to have overcome it's quality control issues. Fit, finish and alignment are flawless.
They're quite quick for their weight, and I like the length for my just shy of 28-inch draw. I usually shoot no.3s on my A riser, but these shoot and feel just as good, and I like the looks (bend of the limbs)of the strung bow a little better with the shorter limbs.
ESP. I think they would make a very shootable, comfortable 62-inch bow on a B riser for longer draws.
