You can see pics of my gates earlier in the thread.

As for the wave, I can tell that it's better but not remarkably so. I'd say like a 30-40% improvement. My biggest gain is that I can fill both rear sacs and not have to drain and fill every time we switched from the regular to the goofy side.

Not much I would do differently except to use a somewhat thicker material as both of my gates broke in the same place but have been fine since I doubled up on the cutting board used on the piece that's up against the transom.
