After going back and forth with tabman on tht forums aka Tom from Bennett Corporation, I decided to go ahead and give these tabs a shot. I know that the SeaArks tend to porpoise at higher speeds and the 4 blade prop and tabs should resolve that, I want to keep the bow down as much as possible and the tabs will do that. They'll improve the hole shot but the Etec will make that happen all on it's own, they'll help get the boat on plane faster and she'll plane at slower speeds and lastly, with over 300 lbs of batteries in or fairly close to the stern, keeping the stern as high as possible is important and these will help with that. At $140, hard to pass on and I've spent more than that for a meal. I couldn't find any reviews on these, they're too new. However, I did read a LOT of reviews on the Smart Tabs and they do work well for the most part. The biggest complaints were related to poor construction. The Bennett tabs are a big step above the Smart Tabs in construction. Ordered the SLT10 tabs.
