I can't really answer your question directly, but you might want to expand your horizon to include the Bob Lee supercurve limbs, called CobraCurve, as well as the ILF limbs you are considering.
My experience with ILF limbs is limited to my Hoyt Satori, which I bought with the Hoyt “premium” ILF limbs for a couple of hundred dollars more than the standard ones cost. The Satori is a fine bow which works as well as I expected, and is a bow I plan to keep in my stable.
However, the Bob Lee Shikari, with CobraCurve limbs, blew my socks off! First, it is the quietest bow I have ever shot. I don't think it would ever be possible for an ILF bow to be this quiet because of all the adjustable fittings and because the limbs are not really locked down. While the Shikari also has quick detachable limbs, they are securely locked down. Second, the Shikari is the highest performing bow I have ever owned. The supercurve limbs have a force/draw curve where a lot of energy is added in the early part of the draw, and the curve levels out toward the end of the draw so it doesn't seem like there is much increase in draw weight in the last few inches of the draw. As a result, one gets a few extra fps without having to increase the draw weight. The limbs are incredibly stable, and it’s nice to not have to worry as much about limb twist, both from the standpoint of damaging the bow and the effect it has on accuracy. For example, when I test velocity on a chronograph with other bows, I usually have a variation of maybe 3 fps in a 5 shot series. With the Shikari I usually have a 1 fps variation in a five shot series.
None of this is scientific, just my own personal experience.
