Thanks for your quick reply guys.
I'm really looking to spend no more than about 250 on this, and the Pulse seems to be a good fit for someone at my level looking for a board not so stiff and not so soft. I was considering the Burton TWC board, but that just seemed a bit too soft and would be a bit rough on the carving.
In terms of sizing, unfortunately, there is no normal waist width pulse that runs between sizes 157-159. Its and then jumps to 160, so if I were to buy a non wide board, those would be my two options, or I could do the 158 but it would be wide.
