Gorgo,
I fixed the slow leak near the junction of the seam and inflated the SB to 14 psi.
Checked it after 12 hrs and it lost zero pressure.
PT, JS and I then took off on the regulation Elwood - HMB DWér enjoying gusts between 30 -40 knots.
I was sceptical prior to the run, but was a convert afterwards.
It required a bit of coaxing onto a runner, but once on, felt solid, stable and controllable.
Granted, it's a different sensation to a rigid board, but geez they work well across most conditions. Packing up at the other end saw no tedious moments trying to strap 3 boards onto one car in the gusty northerly.
