I just added a set of the Samick R3 62" (ILF Long) limbs in 30# draw weight. Can't beat the price at Alternative.

Anyhoo, I did some bareshaft testing with a few 400/500 spines and different weight points. Seemed to find a good combo with the 30" 500 spine and 175gr up front. I need to get some 32" 500's though, I'm short-drawing a bit with these, but they fly pretty well.
