The polymer rollers aren't that much more expensive are they?
Todd, I'd put a cradle under the hull if I were you. Bouncing down the road is putting a fair amount of stress on a pretty small contact patch.
My trailer, I've got a single roller mounted at the back, and a cradle forward of it. The hull only touches the roller when it is being slid on the trailer. You can kinda see it here.
