I have the 145 Jackson and the P wing with 60cm mast. I just started foiling altogether. So far I have about 3 hours on this board and after an hour I was already riding long stretches like 500M in the air. I have no other foiling experience but I think this setup is really easy to learn on.
I have seen other experienced riders try for hours and hours without succeeding on other foils. I don't think I'm a super gifted rider either, I have been riding for a long time but on twintips but I don't do very advanced moves. The Shinn foil may not be the most advanced but I can attest that it's certainly one of the most accessible for people getting into the sport. Other people that I know have reported a similar experience. Maybe after a year or 2 I'll outgrow it but at the moment I'm really enjoying my experience on this setup!
