I don't disagree with you at all but don't think that you have to tinker with an ILF. It can be just as simple as any take down bow.

I do like that I can adjust the tiller since I like zero tiller for my three under shooting, and I like that I can tweek preload if I am just on the edge of tuned with a particular arrow and point combo, or if I have a longer draw and want a the draw force curve to max out at my draw length.

If you like to tweek and have an ILF, you probably will tweek it but it can be just as simple as any take down, except that you don't need a wrench to take it apart or put it together.

I like the versatility and that I can shoot lighter faster arrows for targets or heavier for hunting. I don't know of any other system that will stay together with a steady diet of arrows as light as 5gpp. I can only get my arrows to about 6gpp and be legal tip weight where I shoot , but I still get 215 fps from my ILF 3D bow.
