I'm glad you like the ILF attachment system... But some of your posts border on hyperbole and the fact is that even the best ILF limbs don't perform any better than the limbs from dozens of custom bowyers...or the latest mass produced Bear for that matter.

Here are the numbers on the BF Extremes, which are top of the line limbs. Good, not great efficiency.
