Intermediate rider. Old board was a Nobile T5, just got the 2015 Axis Limited carbon.

Two sessions on it both in fairly choppy water of 20 - 40cm. Found the tail would often slide out just as i'd load it up to do a move / pop.

Need to measure the fins tomorrow. I think they are 40mm. Positioned bindings almost in the centre of the horizontal i.e toe vs heelside edge.

Its slightly bigger than my last board 140 x 43 but i weigh 94kgs. Mate reckons because of extra surface area i wont be sinking as much as i use to on my old board and therefore not digging in as much of the board's rail to help with edging...?

Im wondering if:

1. I need to just get use to it some more
2. Dont take it in such big chop
3. Get bigger fins
4. Mount bindings closer to heelside edge.

Thoughts?
