I too have gone all in for the metal riser ILF setups and have had several.I love the ability to tinker and fine tune all my equipment and nothing is better suited to this than the ILF rigs. I currently shoot a TT Titan with TT Samick Carbon Master Long bow limbs and it is sweet. Accurate,quiet,fast etc. and that with limbs adjustable from #40-44. Some of the others I own or have sold are the Das elite, Dalaa 17", Sky 15", Morrison gen 2, TAC firefly, with limbs as follows; Winnex, Dalaa, Dryad x 2, sky, and TT carbon masters. Liked then all but the one again I've settled on is the 17" TT Titan riser and TT Samick carbon master LB limbs. With this I shoot carbon arrows from 560 gr to 470 grains from 160-175 fps set at #42. Other than the Dalaa everything else has been purchased used off the classifieds. Good luck in your quest.
