Hey there. Looking for a 48-40 advat-edge helix. Currently have a Bender 47-43, came with sled but changing clutching. What advantages would the 48-40 have over the 47-43.
What you going too change the clutching too and why the 48/40 ?
Thought I read somewhere that the advant-edge were acually about 4deg steeper then marked. So a 48/40 would acually be around a 52/44. But I could be wrong
A couple of bucks
