PTM926 is an unbelievable front wing, I use it for wind foiling in 8-15mph and wing foiling in 12-22mph. Have spent hundreds of hours now on this foil, cannot say enough great things about it. It has great low-end chug but also turns very well in all kinds of transitions.
PFI730 is a refined version of the infinity 76, the i76 is a fantastic wing but sometimes had a touch too much lift at times and so the PFI730 just has a more polished feel without the pitch battle, it's also seriously quick for a low aspect front wing and I have got over 23 mph on it with a 5.0.
PTM684 it's in my foil bag but have yet to test it yet.
I made a couple of videos explaining more (BTW when I made the PFI730 video was first time I had COVID19 just in case anyone thought I was talking a bit breathy, lol)
