We had great results with the suction cup mount stuck to the front of the slalom ski looking back. Very nice action. Installed floaty back door and zip tied two floating key fobs on - that was then enough to float the whole assy. Then tied the thing to my front ski binding so that at worst it would get banged around if it let loose, which it never did.
Also clamped it to the boom for barefooting which was pretty cool as well. Haven't tried the chest mount on the rider yet, but aim to do it soon.
