If if was me I would go back with CCA treated wood. I know some people like the rollers but you have to be careful with them when unloading as the boat comes off the trailer very easy and can come off on the ramp when you are not ready. I was also told the boat moves around some on the trailer when the rollers are wet. I was told they will leave marks on the boat if you have a glass boat. Lastly and maybe most important was that the pressure points on the boat change with the rollers and the hull could be damaged while being trailered again I think this was on a glass boat.
