My JD's broke. at about 85 mph it cracked right down the drivers side bty the roll hoop. I would say the Jd's has a small worked verry well but didn't last very long for me. After evaluating it I would say it is made out of too thin plexi to be durable for top down hway driving. Maybee that one is better pecase that seem is not there to break, i would appreciate a eval too. I need a new windscreen :(
