I carried on from Bob Gordon of St. Maries Idaho when he had a floater piece of plague blind him in one eye. He started warf conversions 25 years or so ago to ILF and was the innovator of the short riser ILF stuff in many ways.
He cut down a PSE riser to 17 inches and made a jig to have it welded back.
David Sosa and John Magera kind of re-thought the adjustment slot in DAS out from the old Hoyt Medallion capture system and it became DAS.
Warf originated from Bobs 90 pound Boxer dog and the character with the wrinkled forehead on Star Trek.
Warf is an ILF conversion and Quarf was a bolt down with Quinn limbs and God rest Peggy and David Quinn in heaven.
I talked to them both and they were both the nicest people, not to mention the high-quality limbs and bows David made.
We do not care what they are called but that is the original history and nomenclature and it honors them all when used correctly.
