Clutching for SLP Single

I recently installed an SLP Single Pipe Kit as well as a Powerclaw 2.6 track.

To increase WOT RPM, should I reduce weight or tighten the secondary spring?

Should weights be used to control RPM and the secondary spring tension to control upshift/backshift?

Prior to these changes, I was thrilled with my flat land clutching. I have Dalton adjustables fully loaded to 75g along with a D&D orange spring (170/305) in the primary. I have a 48/44/40 helix with a D&D purple spring (83/140) and D&D torsion conversion kit in the secondary. Also have rock rollers. I had it dialed in to run 7600 RPM, and it ripped.

I went for a test run last night. With the same clutching, I was seeing 7800 RPM. I knew I had two choices to increase my peak RPM, either reduce weight or tighten the secondary spring. It was easy to change the secondary with the tools I had at that moment, so I tightened it two holes. That change has me running 8060 RPM. The sled pulls hard. Lifts the skis way higher than ever before.

I was testing at night, and it was snowing. I was riding in an unfamiliar area, and it was a bit scary. WOT resulted in one of two things, either pointing at the stars, or going way too fast on a short trail. It was quite difficult to tell how well it was working.

Let me know what you think I should do. I can certainly pull a couple grams of weight and sit it back, but I'd like to hear what the experts have to say.

Am I limiting upshift by tightening the secondary? Backshift has always been good.

Well, I made it run at the correct RPM. I'm not sure that means I've figured it out.

Perhaps the thing to do is try it! I'll put the secondary back where it was and pull a couple grams out of the weights. See what happens. Worst case scenario, I waste 20 minutes tinkering. Best case, it rips harder!
