Update!!
I've had a few surfs on it now. Conditions were pretty much the same each time. Clean 2ft plus rights.
The first couple of waves the board just felt right immediately. Just getting into the flow and gently letting the board float up and down the face standing in the middle of the deck. After a couple of those I took off a little deeper and used the tail to carve a few turns. With my foot on the tail pad the thin tail and rails were very responsive, making the big wide nose come around very easily. Swing weight was very low too. Once in a while a bigger set came through and I more often than not found myself a tad too deep. Take off and point down the line mid drop and pump rail to rail from mid deck again and the big girl accelerated surprisingly well. Make the fast section with ease before cutting back at the bowly section in front of the lifeguard tower. Trim the board again and being my stylish shuffle toward the nose

I've mentioned before that my nose riding skills are nothing to be desired and nothing has changed. The wide nose and concave had me feeling very stable up there though.
A few more waves and I felt completely dialled in. Later and deeper takeoffs were made with ease and confidence. After each of my four surfs my face looked like this
Happy as a proverbial pig with this board. Mick has made me a happy SUPer 3 out of 3 times now.
