Boost is overkill some days. That is why i like the 9r. It wasn't enough the other day though.
I'm actually probably over the mono rail. When it first came out i thought it was the greatest thing since milk. After i got my kaos boost and seen how easy it was to take sh!tholing, i don't want one anymore and i do have a mountain max. Just as easy and no drawbacks. I put a 34 inch front end on my wife's sled and it felt easier. My heavy old shredder feels as easy in powder. For those that say throttle control, it helps but its still there and sometimes you have to have it and it will lay you out. They don't hold an edge like a 2 rail. They need choices or I'm not buying one.
