The only reason you need 12 x 12 with Lenco is because they do not go down in the water far enough. The stroke of the actuators and/or the mounting geometry make for insufficient travel. The Bennetts travel farther than you will ever need, but you can fix that by just letting go of the button. When you run out of stroke on the Lencos, you're done. Plus, the 90º turned down edges on the M120 Sports do for the boat tracking what the same edge design does with the Permatrim.
On the other hand - the Lencos are very well made and a good product. There is no hydraulic junk with the Lencos, and that is a major plus. The reason I went to the Lencos was exactly that. But, you see, I done learned my lesson. Those Lenco 12 x 12s should do everything you need on a CD22 and you will be very happy with them.
If you haven't bought those Permatrims yet, I would suggest you try the tabs only first. On my CD22, the tabs provided more bow down than I ever needed; I could turn the bow into a bulldozer at any speed if I wanted. Another benefit of the trim tabs is the freedom to trim the motors where physics wants them to be rather than where you need them to be for hull attitude. With the thrust running square to the water surface, you get the most efficiency and economy. Trim tabs work to force the bow down, whereas a hydrofoil serves to lift the stern and allow the bow to go down. The stern is only a few inches deep in the water when on plane anyway, so given a choice I would think that controlling the bow is preferable to lifting the stern. You should not need both the tabs and the foil unless the function of the tabs is inadequate as is the case with the two gentlemen who are struggling so with their Lencos.
Many, many people have gone through this process of finally getting tired of stretching their neck and sliding sideways in the seat to try and get the boat to stay level sideways and see over the bow. Back in the old days, the guys at C-Dory strongly advised against trim tabs, and it is kind of a mind set among us to put off getting them. But once they are on, we wonder why in the world the boat wasn't built with them in the first place. Now they are a factory option. And either for this model year, or mid-season last year, the factory switched from Lenco electrics to Bennett hydraulics. And I promise you it had nothing to do with my incessant ranting.
I also promise you that I will never make fun of your choice if you decide on the simplicity of the Lenco electric screw jacks over the potential problems of hydraulics. If your tabs have enough surface area - and at 12 x 12 they will have - they will do just what you want.
A couple of disclaimers: I usually get into trouble when I start trying to use words like physics or when I think I have it figured out how a hull goes through the water. Take everything I say under advisement until such time as DoD and SW Joe have had their chance to beat the crap out of me. I am more of a simple minded go-with-what-works guy than a scientific analyze-and-choose-the-best-design person, and when I fail, I do so miserably. I may also be mistaken about the when, why and what fors of the factory option trim tabs - but the way I stated it is the way I believe it to be at this moment.
