Literally no flex on the Lovett Pro with a 150 pound rider.
All of the Calibrated boards come with built in arch bars. James prefers the taller arch bars from the Board Shop, but felt the traction on the Lovett Pro was more than adequate. Also, the rear pad comes with a kick pad built in. Overall, a very nice job with the traction, without having to buy an aftermarket set.
One of Jaime Lovett's nicknames was Shuvit Lovett.
The pro model is true to this name sake. It shuv's effortlessly and lands with stability.
