I was in a similar situation back during the summer. I read every post there was about ILF's and was able to gain a little knowledge. However, you have to shoot one to have the full experience...that is where Morrison Archery comes into the picture.
I was fortunate enough to be working on a project near Morrison Archery. So, I contacted Bob and was able to visit his home where I was able to shoot his line of ILF bows.
Long story, but the short of it is I have one of his new metal design risers with carbon/foam limbs. This thing is so fast and accurate if I do my part that it has brought my shooting ability to a new level.
Like someone mentioned, contact the couple of references mentioned and see if you can do a trial/test. You will not be sorry and I will be willing to bet you will walk away with one of these rigs.
