Do some research on the Nobile NHP. An excellent product. The click and go fin,binding and handle is excellent when traveling. In our shop, the 134 x 42 is the best selling model.
I have rode the 2 Slingshot boards you have mentioned. The Crisis is their entry level board offering solid performance at a great price point. The Asylum is a more freestyle board with a good rocker line with a flat section to enhance the upwind performance. The Slingshot pads are very comfortable and have a large adjustment for boots or barefoot.
There are so many choices and impossible to ride all. I don't really go on and on about TT's, they IMO are all very similar except for a noted few(Ocean Rodeo Mako, Shinn Speedball etc). That said, the Nobile NHP ticks all the boxes. Speed,pop,upwind and smooth. Great light components. You will not regret buying that board.
