thanks you both!
@dj very nice test. there are no gps results (or i missed them) but it is the most complete one I 've seen. great work and VERY helpful.
narrowed my choices among the two surftechs.
any suggestion among the bark and the jm?
@ScarbsSUP thanks for the invitation but unfortunately i am not in Perth right now (and for some time). But i do appreciate the help and the results you will have. I am really interested on the jm speed. I hear it is a great downwinder but i have no data for speed.
