While wagging the Guy Cribb course beach tip sessions {not all}, used isonic 112 carbon with a 7.8 severne overdive and 38cm weedfin [first time], at second visit to Invy Anderons Inlet, Tracking shows no good jibing tho... BTW, big thanks too Invy WSClub crew for a great time and organisation for the Cribby InTuition course, [pity I did not make the wave course as well next day...] Will probably do it all again next year if it is on again!
