I went for the ILF longbow limbs (don't have em yet, though) because, like JC said, the riser is more deflexed, and the weight adjustment is very nice. I've had a couple of Shawnees, and the smaller straighter riser was harder for me to shoot accurately. The ILF with recurve limbs is the best shooting bow I've shot. I figure with Bob's longbow limbs on it, I can't lose. :D
I'm not sure if I would call the attachment system "ugly"; maybe functionally appealing instead of aesthetically appealing.
