I just jumped in and bought a used Hoyt epic ILF and I am liking it a lot. It is a learning experience for me with learning all the different limb combos and all, but so for I am shooting it better than my Widow. Plus I switched to three under and going have a go at fixed craw.

Its not for everyone but once you get into it there are more pros than cons.

I'm doing the same thing right now.  Can't say I'm shooting better yet but trying to change my shooting style and anchor.  I am impressed with the speed of this rig and seems to be pretty quiet now that I have it close to tuned.  Shooting a Satori 19" w/med TT 2.0 limbs.

Yeah, I just stumbled across Matt Davis selling Satori Risers at firesale prices and I plan on doing the same, I already have some Ilf risers and limbs, but wanted to give the long metal riser that can handle higher poundage limbs a try. Going to give Fixed Crawl a chance.
