Boat is a Tracker 175txw and I never have the winch strap unhooked unless the boat has water under it. One option is cheaper than the other and when loading I do have to wet the carpeted bunks for it to load correctly so there's that...basically I want my bunks to be slick when loading. Also have a pair of keel centering bunks that was a popular mod for the trailers for the Revolution hulls on here for a while. Without them loading is a nightmare. Today I noticed one of my keel centering bunks was basically being held together by the carpet and not sure how much life the other three have left in them. Given what I just said about my particular rig and habits which would you go with?
