    Thanks so far. I tried with a 44/38 but it really really hated that set up, rpm was all over the place, like if my mains were clogged. I think I'm going to try a washer to the tip, maybe even a small nut, it gets almost 8100 rpm now.

    I'd like to run the green spring, because I might use this sled for some towing also. It also seems to feel much stronger with the green spring. The power curve of this sled reminds me more of a turbo machine than a regular one. What if I buy a 40/43 reverse cam helix? Looks like I need to have a steep angle to keep revs down on top end. It's like a 20-25 hp sled most of the low range, and then it tops out at 87 hp.

    So maybe this will work then?
    Primary: white hc spring. Max tip whic should be around 7grams with a nut on the other side. 4,2 gr heel, maybe even 5 gr, because it loads the entire range.
    Secondary: Green@60 deg. 39 deg helix. The less wrap should keep the revs down some also. This will be my last set up in the 17/18 season.

    Will it ruin my shift curve if I try some weight at the center?

    no, it will just make it not as responsive, it might like the weight split thru out the weight and then run the straight angle helix if that's what it likes.
    It's just a little 700!

    Update 9 c or 48f at the place I was going to, no more tuning this season. I am hoping that the engagement shim and less helix angle will make it get rid of the rpm dip on top and to get proper wot rpm also.

    What happens if I run a stiffer HC (gray) primary spring? Will I be able to get away with a steeper (41 deg) angle then?
    What happens if I run a Hauck or yamaha spring with less end force? Does the required helix angle go down too?
