Pinecarpenter, why are you argueing against guys that have proven setups with these sleds?- not speculation. I have two XLT's that I've owned for years and I learned early on the stock setup SUCKS! They come from the factory with conservative gearing and clutching and respond very well to more aggressive setups for clutching and gearing and there is no one "magical" matched set of springs you have to run. Right now I have a spring and helix combo I'm running in my secondary that not many guys would dream of running in an XLT but, for me it works great- ask Madcow!!
