at first glance I would be concerned about the bottom angle of the pipe. it looks like it's flat to the bottom of the boat. most of them I see have a taper on the bottom that angles it from the front of the pipe to the back. while under movement, I believe it helps direct water around the pipe and not up it as hfarr's shows.

the old platform brackets on that year skiers choice have a lot of slop in them. as you mention close proximity to the wakeplate, make sure that as your platform bounces, you really have the right amount of clearance and knowing how the potmetal wears at the points each bracket slides into the transom mount, watch for added wear. those brackets were the only real gripe I had about my '06.

good luck with your water test.
