I have been learning on a axis 1020 (old s series) foil and I'm ready to step down to something smaller, find the 2000cm too much lift now. I will be mostly using it between 8-18knts wind speed before I go back to the windsurfer on fin. Weigh 85-87kgs depending on how satisfying the morning evacuation was

and using a 6m Slick wing.
So my question is will the HPS1050 be too advanced step up (slalom windsurfer so enjoy speed) and should I go the BSC970 ?
also is the 1500cm area still too much for my weight with the higher aspect foils ?
Thanks
