The ilf recurves are very adjustable, you can adjust the bow to shoot a certain arrow instead of you having to find the arrow that your bow will shoot. The tunability of the ilf world has no close second. I have a couple of wf19 risers and Sebastian flute elite+ limbs on them, a very smooth combo with good performance. I don’t agree with Ar1220 because there has been an explosion of shorter, hunting risers since DAS came out with the kinetic hunter. Before the DAS was the warf bows which were old compound risers machined to fit the ilf limbs onto them. The reason for doing this was to have a shorter riser because you gain about a pound for every inch that the riser was shorter than the standard 25 inch ilf target riser. This would give them hunting weight bows that were more maneuverable. Now there are too many manufacturers to name. Lots of great ilf info and history over on Tradtalk.
