PBB Helical 1-12 Fluting

Does anyone have a helical flute? I’m curious how Preferred’s new “Helical 1-12” fluting looks… Thanks!

Like this? This is not a Preferred. I don't recall the twist rate.

Maybe? Lol. Just trying to visualize the difference between what they’re calling helical vs spherical. Maybe it’s even a “gain twist” type of fluting? Guess I’m calling tomorrow.

The names of the particular flutes can certainly vary between the providers. Good Luck!

FWIW the fluting I posted is called "TAC 8" by the guy that did it. He does a TAC 6 with 6 flutes.
