Does the burnt paint make it go slower or catch less fish?
I have the side bunks on mine with about 2" clearance on each side, and I always back the trailer far enough into the water to wet them. Then I pull up the ramp so they are both out of the water before trailering my boat. I've never used the roller type, but think they might be a little better.
To me, side guides are very handy and I wouldn't think of leaving home without them!
