Hi guy's I haven't been on this board for a while, I hope everyone enjoyed their holidays. I want peoples opinions, that actually own different brands. Are Hambys keel protectors worth the extra money, over the self installed brands? Also, what about the tech 5 keel guards? I can get a decent price, for a hambys, but it's still triple the price of the "keel shield" ,or the "keel guard" brands, seen in BPS catalogs. Any, and all opinions wanted. Thanks.
