Well after a full day yesterday of riding at 7500 feet with pretty good conditions, maybe 1-2 feet powder over a good base here is my final set up after messing around with the clutching a LOT over time.
16 axys
SLP pipe, diamond can 163"
primary... MTX weights, 68 gr
primary spring 125/333 titanium,or slp blue/pink
secondary.. helix 56--40 .36
black/purple spring, 2 delrins
Sled pulled 8450-8500 on the flats up there and 8250-8350 in hard climbs.
all in all I really like the gear down, allows full shift out a bit better and nice low end grunt improvement, however it is in no way a necessity as sled really runs great with the pipe can combo, basicly runs better than my friends 13 pro with the stage 4 slp kit.
