If you gear down AND you have put the heaviest rivets/bolts in the tip of the weights and the sled still overrevs, what are your options?
I wouldn't like to go softer on the primary spring because I think the sled might bog down if you hit a little heavier snow. Or will it?
I don't want to go soft on the secondary heller because I want to have at least some backshift (minimum 70 deg green)
I guess the only thing that remains is the helix, which you can use a steep finish angle on?
What do you think?

1. What helix are you using now?
2. What weights are you running?
3. What sled is this for?
4. Over revs by how much?

I am asking on a general basis but the info is below. I am discussing that on another thread.
Whats your set up with the srx that even has been ported? Especially interrested in the helix angle.
50/38
hc 401-0
2002 srx
overrevs by 200-400 depending on gearing

Well I just got done testing almost your same exact set-up.. I used a 51-38 Dalton, Red clicker primary, Stock 2002 gearing, Green secondary @ 60.
I ran 6.2g heel and 6.4g tip. I had to go to 60 degrees on the secondary to get RPM's close. It was running 8500-8600 on a longer run. Here are the results from my testing:
51/38 Dalton – Sec w/ Green spring @70
5.4 Heel
5.6 tip
8700 entire way
6.2 heel
6.4 tip
8600 entire way
6.2 heel
2.5 center
6.4 tip
8450-8500
6.8 heel
2.5 center
6.4 tip
8350 – 8500 but DCS is coming on for all of these set-ups. Comes on between 90-100mph.
Sec spring @ 60
6.2 heel
6.4 tip
8450 – 8500....8600 – DCS still coming on.
I wanted to keep weight in heel and tip so I went back to the Advant-edge 48/40 and have that dialed in to hit 8300...then to 8500 on a long pull. I was just looking to try something different this year. Note - To get the 2.5 center weight, you have to cut down a small bolt. I also have decided to disable my DCS this year since I have made no motor or clutching mods and the light still comes on. Tried the octane boost, rubber washer, etc...

I even tried 8 grams in the tip but that made a nice groove in my spider. (Nuts that fit the heelclicker bolts)
I have to grind 2 mm of the nut "height".
I have lots of test results at home, I am there on sunday.
Let's keep in touch..
I am also working on the dcs thing.
I noted that your sled is ported. That might enable the dcs because I guess the head chamber design has been altered..
