PB,
I cut the tail based on my memory of an Uncle Josh (UJ) pork rind that I fished some time ago. UJ has been sold for many years. So, I like my trailer's chances. Also, the jig is a brand-new, one-of-a-kind design for me that I haven't fished yet.
Most of my "leather" fishing, so far, involved jigs with cut curly-tails. Have not caught any large fish on them yet, just plenty of small bass.
Leather behaves like pork rind in the water.
