boat trailer question

[oteps]

I have a 86 v20 . The trailer has rollers on it right now and its a pain to get loaded up straight. It seems like the rollers hit the ribs on the boat, I looked at it and if I adjust them I still think it will be a pain to load. Would I be better off running 2x4's with carpet and getting rid of the rollers? Yes I am new to boating so maybe I just need to practice loading it up more? Most of the time I have to back the boat into the water 3 or 4 times to get it straight. I know someone has to be the idiot at the docks but I dont want it to be me anymore.
