Too bad you didn't try em Ferm.... I think you'd have a much different opinion...
I've seen before and after on a bunch of boats and several of them were tested bare, with a foil, and with smart tabs.... The tabs, far and away worked the best in every case.
Being able to adjust tabs is a benefit most of the time tho there are a few times that the smart tabs are actually better than the adjustable.... Admittedly being in the big water, the adjustable have a big advantage with the following sea thing....
That said, smart tabs are soooo much better than a foil on the motor...
I actually considered retrofitting my (inland only) 28' twin V8 cruiser from hydraulic to smart tabs but they don't make em for a boat that big.
