I took the new 4'6" out for a second time (first being New Years so this is actually the only board I've surfed all year). I bolted on the Go Foil Iwa on the 29.5" mast (with the 3" extension) as the tide was a dropping high (2.2' when I went out).
I got two fun rides off the bat - and with the tall mast, being up off the water that high was a blast. But then I ran into a spell of weird conditions where I couldn't catch a wave and ride. I'd get thrown (pretty hard on a few) and actually no one was catching - the wind was howling by this time so I decided to catch one more good one in. Three mediocre waves later I caught the good one but still had to paddle in. Here is where I had the foil set. I think I can drop it a notch further back in the tracks.
So after a couple of sessions on the 4'6", I'd say it is demanding of what wave it'll takeoff with, it is demanding on takeoff - timing is critical to go or no go, and it is lower in literage. I'll keep using it, but it may be a board I can use to kite foil. If I go tomorrow I'll ride the 4'10" and the Armstrong - might work better in these sloppy conditions.
