    Favorite trim tabs for the X4 skis?

    For those of you who have tried trim tabs on your XPs and SPXs, what did you like or dislike about them? What seems to work the best and why? Adjustable or fixed? I've seen several styles that cover a whole range, so I'd be interested in hearing what others think in order to narrow it down.
    Thanks!

    I had a set on my 96xp and you can really throw the ski around and spin with them. I sold them and the first thing i noticed was that the ski didn't wanna whip around as easy when i was setting up for some waves. Im gonna get another set again. I had the ride plate extention also.

    I didn't like them. They forced the hull down into the water, making the trim above 1/2 useless. They also really loaded the engine, with a piped setup you could easily squeak one if it was not setup a tad rich.

    I have a set of R&D standard if you are interested in them Zig.

    + 1 , i totally agree with 96XPSS
    also when i took them of my 96xp,the ski leaned over to one side at about 30mph and was a nightmare to figure out what it was.It was that i didn't silicone the black originals on right and it craeted a "vaccume' effect.So what ever way you go make sure you glob the hell out of them and trim it with a razor when it dries.

    The best setup for my old '95 XP (717) was the stock tab shimmed down 1mm-ish (I slid half a 5/16 SS washer in behind each bolt between the tab and the hull).

    This gave it better stability and you could still lift the nose with the trim. I did not have any yaw issues with just the tab adjustment. When I added Worx sponsons to it she wanted to chine walk a bit in that same 30ish mph range (dip from one side to the other, though it did not really affect tracking, it was annoying). Above that speed it ran true with any trim setting and the tab adjustment took a lot of the porpoise out of it in the chop. When I removed the washers from the tabs and ran it with the Worx the chine walk was less pronounced and it wanted to porpoise again.

    This was with an R&D intake grate.

    It DID slow it down on smooth water, but then it was only a 717. Lost about a mph on glass but in chop the drop was negligible.
