Good discussion. My stock fender chops decided to go hang-gliding off the jeep on I-15 doing 75mph on my way back from Calico.
Even though some club members and myself did have fun playing reality-Frogger on the freeway to retrieve said run-away fenders, I am taking a serious look at some tube ones now. Those stock fenders, even trimmed ones, come off super easy after a day of hitting canyon walls and being stuffed with more rubber than WayofLife's booty-hole.
Ive seen Abendx try his out against an embankment on BC109, so I'm convinced that the PSC ones don't mind being bitch-slapped by the trail.
