I have the chance to get a '06 SJ Expert(Green demo bike) which I mainly want for trail riding and some racing. I have a Racer-X 80mm for a race bike. I also have a Turner Burner(with 4" not 3.5 travel) right now as a trail bike which I'm going to sell. I have on occasion had to race the Turner when the fork or crank broke on the Racer-X. Having rode a 4" trail bike(the Burner) will the SJ feel "mushy" with 5 inches of travel? Can the SJ still be competitive as a race bike with my light wheelset? Is the 06 Epic a better Trail/Back-up race bike? I can't test ride these so I would appreciate any input.
