I just recently decided to try both recurves and ILF... now I'm kind of going crazy on two fronts... old Bear recurves and ILF risers/limbs. (One has nothing to do with the other...)
As to ILF, I got the Trad Tech Titan and really like it, and shoot well with it, which is more to the point. After years of just Hill longbows, it's an adjustment to the weight, but as someone mentioned, it's a tank... you aren't going to hurt it, and I'm having a ball with the changeable limbs. I also got a TT Pinacle riser, which is a lot less expensive, and wood if aluminum bothers you. I like the Titan better, because it fits my hand better. The Pinnacle is a bit "massy" for me, and actually, I resold it... not because of that, but because I was lucky enough to get two Morrison ILF risers... best of both worlds... beautiful custom wood and ILF.
So, my ILF stable will consist of a 16" Morrison riser, 17" Titan riser and 18" Morrison riser. With five sets of limbs, both recurve and longbow, I can literally "build" a bow in the bow room each time I go out to shoot.
What I'd really like to see is someone bring out an ILF riser that is shaped to longbow norms, rather than recurve.
