Stuart has a home built NC machine and makes really nice boards. He has done a couple for me now and I am very happy with them. The board that he based this design on is a 70cm x112 ltr slalom, it is a ball tearer, I couldn't be happier. I have had it close to 40knots at SP with a 37cm Slalom fin in it.
You can see it in action on Colins awesome Sandy Point Vid.

I made a mistake in the CAD file I didn't pick up and the nose came out a bit thick but apart from that I do not know what I would change if I designed another one, it works just great.
Give him a yell if you are thinking about a custom and if you need some design assistance Stuart knows his stuf or I am also happy to help out with design and CAD file.
