Hi i recently got my new Quobba FINS from Taryan over in WA . Have had 2 great surfs on my sunova 10ft x 29 style with large side bites and my favourite 10 " bommerang fin .The board was fast , better control and just GREAT . Thanks to the WA team and also Sup The Greek Videos . Had another surf today , knee to shoulder glass , was a bit bigger yesterday BUT , these fins do work .I wear a Rip Curl Search whatch which allows me the data to see all this happening .Just adding i am 70 yo about 74/5 ? kg in the winter gear , as i live in Taranki New Zealand
