Local Albertan here (albeit, boat lives in Invermere) - i have the same 2014 F22 as yours.
I've got the same stock ballast hard tanks (filled 100% on surf side, empty on other side), suction cup wedge (mission) on the opposite side, and a pair of 500lb sacks that i always keep full (lazy), Cav plate usually 1/3-1/2 way down and we can pull some pretty good surf waves. Lots of folks have surfed behind our boat and can't believe (for the equipment) how good it is.
Can i ask what speed you're going? I didn't see it above. We are usually at 10.7 mph. I found speed made a huge difference on our wave. Our (non-lifted) platform doesn't affect the wave either.
With that said, I can't find a picture of our wave now. I'll post one if i can find it.
