Cheers for all the advice! Very helpful.
I managed to get out yesterday on some flat water this time. I changed my fins over to the Cabrinha fins fro my old board. It felts a lot better that the other ones, much more like my old board. I didn't stay out for long as I had injured my ankle surfing the day before, but the short session I had felt much better.
One thing I'm pretty sure I have wrong is my foot position, I read a lot that my feet should be right on the rail with only the ends of my feet in the straps? When I try this though I always end up getting my heels dragging in the water and pulling me in? Could this be because i'm not keeping the board flat enough?
To be honest I think what I need is a lot more time in the water, I get the impression riding these boards well doesn't come over night? Thats what I love about it all though, the challenge of getting it right.
I have attached a picture of me from yesterday, if you can spot anything obvious i'm doing wrong then please let me know.
Cheers
