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.
 

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
 
Changing from a Bender Red primary, with a couple engagement springs, to a w-w-w and loaded dn20's. want to make it more trailable
