Hey thanks guys,
I have both fixed and chicken on and am learning in the surf (and doing a fair bit of walking). I have been wondering the same things - ta for clearing this up for me.
I am sticking to my fixed at the moment, so I have a little more time and brain resources to stay clear of others and pretty much anything dodgy! I can see how the loop will be handy soon though as I am really sick of walking upwind with an otherwise comfy seat harness, giving me an atomic wedgy.
Just a quick tangent too - I have a Naish TT 2003 4'9" (142cm x 37). This board for a 2003 vintage is stiff and seems to have a pretty standard sharp style rails which I find hard to get much "bight" out of (even though it's an eight fin board). Now i think at 80kgs in gusts on a fixed bar or in the hands I should have a little more leverage than i am getting without crabbing sideways or geting slipped onto a flat plane. Wassup?
I should say as far I am learning but far as edging I wakeboarded and used trick skis (fast) for years and know how to control an edge at speed even without fins. So what's up have flexi boards (as is the current trend) really got the edge?? Bad pun I know...
cheers,
