Look if the str works for you thats great!! I however see lots of potential in the Hellfire, both positive and negative, once I have repaired all the design flaws I can work on the positives, kick up, multible" A" arm changes.. theres lots of room to experment!! I like to race almost as much as I like to build.. the STR leaves one with only one position for all, and I repeat.. all A arm set ups....... you can only wonder whats outside the box!! Its a great product!! the STR that is, works for guys that !! well we could view this from several ways ..... however lets say have more time to race than work on set ups... ?? fair! some of us chose to work our own paths !! off the shelf or what everyone says is good isn't good enough!!, I however long to see the best in everthing I do... Therefore the hellfire provides the path to experiment!! Not just run someone elses set up!! And yes I have a great imagination,, therefore I wonder chickenfarmer!!
