Nope it's not ILF, it has the Formula limb system like the Buffalo. It looks like a short (21") Formula Ion-X riser w/ short limbs for a 62" hunting style bow. It's a 40#'er so should adjust from 37# or so to a bit over 40#. Should shoot pretty quick with the long riser and short limbs - about right to my way of thinking. Of course I thought that about the Buffalo I had also and it has a new home...time will tell.
It's a new bow. Just enjoy it until the next one, if you are an addict like me. I'm going to drop poundage. I've been shooting 48 lbs on targets and 55 lbs hunting. I didn't shoot for over a year because of a shoulder injury and I can really feel the weight now. I can only get a couple dozen good shots before the weight starts causing me to get sloppy. I'm just not as strong as I was before the shoulder injury. I think I'll get stronger but I'm going with lighter limbs for a while.
