That's cool to hear guys. (Well apart from the knee injury, get well soon!)
I am a 2-stroke rider for life. A 150 is every bit as powerful as a 250 4-stroke, it's just really different. you have to "work" all the time. It's just like a hopped up 125, and it's sooo much fun.
i've had my share of injuries also: Broken femur, dislocated shoulder, broken forearm, broken bone in my hand...
Maybe that's why I got into RC...Here I can hit a triple wide open, and still be confident that all my limbs will remain intact
.
My money is on Ken Roczen/Josh Hansen and Ryan Dungey.
