Wooden vs. Composite Bunks

[muskynut]

Looking for some info.....my bunks on my trailer are rotted and it is time to replace. I see that they have composite bunks available now. I have a pretty light weight boat (aluminum) ; was thinking of purchasing composite bunks instead of wood. Anyone have any familiarity with these bunks, use them? or have any information regarding them? Is it worth getting the composites over treated lumber. Any feedback greatly appreciated.....thanks....Capt. Dave
