I'm wondering if anyone can find something wrong with the scientific justifications that the makers of the Wavegrinder fins provide for their fin design.
I searched Swaylocks and found two previous short ride reports and discussion of these fins. Other ride reports from the web also seem to be exclusively positive, at least for an amateur sort of internet search.
I have read through their pages and cannot find any obvious fault in their reasoning.
I have also lent a Wavegrinder original fin to a much better surfer than myself, and he found it to be his favourite fin immediately. I have only surfed it once myself, then went back to using McCoy Gullwing fins for no real good reason, other than that I know they work. So basically I have not tested these fins myself, one session in poor conditions does not mean much.
Having messed around with attempts to make a fin for almost a year, I decided a couple of days ago to buy 4 small, 4 medium, and one large Wavegrinder fin, all of the 'semi-flexible' variety.
I reckon they have nailed it, or are at least very close to ideal fin design, and I have no hope in hell to ever stop wondering if I'm missing out if I do not try the fins out myself.
And no, I'm not paid in any way for this and I just paid full price for the fins from their website.
