I have Bennett 12" too, they work great. "30 + years" WOW!!! It would not be the same ride without them in the 2-3 bay slop here in Tampa w/ 20 + knot winds. But if I was to install new tabs I would consider the QL tabs.

I have no experience with them and have heard mixed reviews but removing the metal from the back for fishing and safety could go a long ways.
