I have had several sessions on the Shinn Turbo 132 x 42 this summer. I sell Shinn as well as other top end boards. The board I will compare to is the Nobile NHP 134 x 42 which IMO is an excellent TT. On to Turbo. The first thing is the Sneaker X Foot Pads. Super comfortable with excellent grip on your foot. I ride barefoot so I can't say how it will be with boots. I've had customers say they would like to see a toe rail grip on the foot bed. The stance width on the board is your average free ride setting. A freestyle guy or girl might think its a little narrow. The fins are 57mm. They provide solid grip and nice "Bite" when carving the board. Being a little large ,they are sticky in transition when turning the board.
With the independent flex on the tips, the V Twist Technology translates into a real world smooth carve with plenty of grip from the fins. The Turbo is very fun in mushy 2ft -4ft waves. I found the board likes power for the best upwind performance. Because of the very short rail length, the more juiced you are,the better the Upwind performance. Very smooth in the chop, maybe not as good as the Monk but pretty close. Top speed, excellent with good control, like any quality TT.
In back to back testing with the Nobile NHP(like talking a couple runs, one after another with each board)a couple points really were noticeable. Number one and the biggest is the weight. The Shinn Turbo felt noticeably lighter than the NHP. Number two, the foot pads were so much more comfortable( I have no problems with Nobile footpads). Now honestly, I feel the NHP is faster,better upwind and has better pop. The Turbo feels smoother,carves better and IMO just looks killer!!! lol.
Thats it, I've been using the Turbo a lot and if you want a super nice smooth TT with great foot pads, put the Shinn on your list to try.
