Bender Helix's
For a couple years now I have keeping track of all the different Bender helix part numbers and their specs that are given on this site double checking the answers with my list. I have found that this is a very popular subject on here. Their is one guy on here that knew most of them I think his name is Doug. Here is the list I have came up with off this sight:
9760 - 49/45
9770 - 49/37
9770s - 51/39
9770tp - 51/43
9860 - 51/45
9870 - 53/43
9970 - 43/35
2070 - 47/43

Is this a good helix to run with heel clickers in a stock 01 srx.This is the helix bender recommended,i know a lot of people say you should run a 50/40 but bender said it was too steep and only good for short drags.
