If you're on a real roadie and want to get going fast, I would steer way clear.
I was running 700x38 on an old Cannondale hybrid and the gyroscopic forces that those tires generated was surprising. I never had a flat on them but I haven't had a flat on Panaracer Paselas either at half the price and weight so for me the Plus is just unnecessary weight and expense.
