Well, my opinion does not count because I'm involved. However, I would expect the objectively-measured performance to be very good from anyone's perspective. Subjectively the limbs are super-stable, extremely smooth (see Blacky's independent testing results on a set of ACS RC ILF limbs), and have an interesting almost "let-off" sort of feel toward the end of the draw. That's the static tip camming over.
By the way, all consumer-archers should assume that all bowyers lie (some maybe more than others
) - especially about performance when expressed in terms of AMO/ATA speed. That's why we only quote third-party test results. With the ACS RC ILF limbs Blacky got 198 fps at 28" of draw with a 9 grains per pound arrow and with the hunting-weight string at a nice high BH. The bolt-down ACS RC limb set up similarly is about 5 fps faster than the ILF because the total system of riser & limbs are optimized as a package.
Ultimately what Mike or I think about the limbs is much less important than what our customers think. I hope everyone who gets a set enjoys them as much as I do. Two days before leaving for Africa with mine!
