Need trim tab advice
 

Guys I have a 34' Powerquest Vyper that came with Insta Trim Tabs. I am wanting to upgrade. I bought a pair of used 280 K-planes but they are missing hardware and in not
quite as good of shape that I was led to believe so I'm now considering some of the kits out there, specifically looking at Mayfair. Anybody have experience with them? In looking
at them they don't appear to be as heavy duty as the K-planes but I think would suffice for my usage. TIA
