just wondering if anyone has used these foils with thier slalom gear with any success?

i tried a set of these in my JP 85 wide slalom board and struggled to get them to fly the board like I can with the RS Flight AL foils. I kept moving my mast track back til the foot was almost out of the track but the board still kept wanting to touch the water constantly. I had the rear stabiliser in the highest lift position as well. Any thoughts?

Cheers. :)
