I've got 2 kits that I tried on other sleds. 1 thundershift with 52-44 helix that I ran on RX-1, worked good to mid 90's ran out of top end may of had to much finnish angle. #2 proline I ran on my apex ,engage 4000 top rpm's 10700 slightly over reving on top end. dalton 035T helix not sure of angles . what do ya think a good starting set up would be? Or i could just sell these and buy one already close. thanks. 
The nytro,s stock helix is 43 degrees so what you got is pretty steep. I am gonna be playing with hc,s & supertips this winter with helix,s close to a 46/40. The apex/rx-1 will pull a lot more aggressive clutching then the nytro. You gotta tame down what u got...by a lot.
