I have the HPD standard clutch kit and I'm wondering how much difference adding the helix will make. What helix should I use? I know I should just call Rick but I wanted opinions from you guys. Thanks!

 

If you are going as far as buying a new helix, put up the extra dough and get the roller action kit. You won't be dissapointed. Not sure what helix to use on the 400. On my 500 and the 250 with the roller actions, Aaen sent me a 42-36 helixes. A little tip if you go this way. If you go with Aaen ask for Alana, when talking to her ask what kind of deal she'd make you on the roller action.
