Heard back from PPC on the low end for the 2.7m:

"The low end on the 2.7m is around 25 knots, depending on your foil & weight, and the 2m is around 28 knots."

The low end change from 3.5. at 12 knots to 2.7m at 25 knots is a pretty big leap, they definitely seem sized to bridge your quiver there. I think if I pull the trigger I'd lean towards the 3.5m at the moment. I'm pushing pretty hard on smaller foils and boards and snatching up a tiny double skin might not be the right call.

I was honestly hoping the 2.7 would be my perfect sail and cover 20-40 knots. That would see use almost every day for me and then I could have something tiny in reserve for 40+
