You can get either the elka or the raptor shock from Darrel. He is pushing the raptors more these days but he told me either shock is just as good as the other. His skid is a coupled T motion and I have ride 2 174 sleds with it and they both handled great. One 872 and the other a TSS running 10psi. Held the power of both with ease.
I am running a Toms E motion on my turbo 162X3 and it's gonna take some time and effort but I think I can make it hold the power but we will see. It does ride great and drops a lot of weight compared to Darrel's skid which is the main reason I tried it. If I can't make it hold the power the way I want I'll be selling it and getting one of Darrel's skids
