Si - I think you call it a double concave. Maria, I don't use wax. I hate it melting in the car and sticking to my wetsuit. The front black pad is just a rubber traction mat. The hexagon's are a type of grip and are called RS Pro. Do I slip on this. Sometimes but rarely, certainly not enough to send me back to the wax option.

Here's the board Clayton made for me. Tried it out for the first time today. Loved it! Can't wait to get to know it better. Dimensions 6'6", 21" x 2 3/4" 42ltrs. Thanks very much Clayton, I am so looking for to start Line 2. 

PS Turn around time? Felt quicker than I can make a ham sandwich.

I should add that this session was the first time I have gone left in the pool. My previous session was a right hand wave and as I am reasonably happy with my take off now I decided to move on to Trimming. After about 20 waves I don't think I got on rail at all.

Was it me, the small wave or the board volume. Without any OMBE insights I decided to try a left wave for a change. I found heading down the line difficult, I either surfed or fell off the back of the wave.

But when I played back the video I just thought while I was lying down trying to get behind the surfer in front I actually managed to momentarily get on rail.

Thanks for commenting Graham, Alessandro and Scott I am going to go get on my bosu ball right now.

Do I get on rail while I am trying to get around this young man?

I am struggling trying to trim on this high volume board
