I'm still on the fence. I ride 50% at home 2000' and 50% at 8000' in B.C.
The m8 already has the 36 degree helix and lighter weights for riding high elevation. I need something that will work down low too, so I might try mels stuff. When I go west I'll take it with some adjustable weights. If I can't make it work on the first day I'm switching back to the stock stuff and looking elsewhere. All the other kits seem to use something very close to a 44/36 progressive helix. So they should be pretty close in performance. Jimmy at BMP or Kelsy at RKTek is probably the way I would go. Or...like you said, just go with the sure thing and forget about it.
