I wonder what the real math is on inclination, SCR and flex combining to create the actual turning radius. Complex, I expect.
I do know that on my Jones Flagship even though I still kind of suck at softboot carving the radius of 9.3 m feels pretty short. When I push it, it tends to hook around faster than I like and I lose the tail so I need to figure that out. My heelside needs a lot of work.
When I was shopping for a softie board I saw reviews that said boards like the Yes PYL were good for carving, long radius turns and going fast. That board has around a 7 m sidecut, this does not compute. Do these guys have different definitions of "long radius" and "fast" than I have, or do they actually make that work somehow? My NFC with the 12-14 m sidecut feels stable at speed and does long radius well. 10 m or less feels twitchy to me at mach schnell.
