http://www.mmwatersports.com/able/showprod.cfm?&DID=6&CATID=43&ObjectGroup_ID=434 Just wondering if anyone had some recommendations on the Boss Board Racks. We are getting the Boss Adj. 2 Board Tower Rack. Are the adjustables any more prone to coming loose than the racks that are all one piece, ie. Boss 2 Board Engraved Rack with Logo?
