23' CC trim tab selection

[ripndip]

Hello, I would greatly appreciate any information regarding trim tab selection for my 23' CC with twin 150 HPDI's on 6" setback manual jackplates. I am currently running 12x12 Bennetts mounted fully outboard which I upgraded from the 12x9's that came on the boat. I feel like more tab would definitely help due to the stern weight and extra equipment I have on board (AGM batteries, fresh water tank, radar, two anchors, etc etc) I was looking at the Lenco heavy duty 12x16, or the Lenco high performance 12x18. The 12x18 is similar to a "K plane" and has a pointed end. I have spoken with Lenco and they told me there would be little difference in performance between these two tab sizes due to the taper of the 12x18. I like Bennett trim tabs, but I don't think they have anything like these without going to two actuators per plane. I also like the speed of the Lencos and the built in indicators/no hydraulics/pump. If at all possible it would be great to speak with someone with a similar boat/setup/experience. Thanks so much. Skyler
