Found this on lost's website, pretty much explains it all, mayhem is awesome shaper, and you can ask him anything on his blog and he give you great feed back. It no wonder the FW crew have a great relationship with him.
Bring on more mayhem shapes in FST I say.
"So how long have you been working with Taj on boards? There’s a clip of him riding Mayhems at San Clemente from a couple of years ago, right?
I had made him boards off and on in the past – back when he rode for Webber and I worked with Webber a lot. This new run started in September 2010 before the Lowers event. Taj came over early and was hanging round with Kolohe, he tried one of his boards and ordered some up. We made a couple of batches back then, and with my relationship with Firewire we tried to do a Firewire version of my design. But I wasn’t as good at translating the files as Nev is, and mine didn’t come out as good as the ones he was getting from Nev.
But last summer we did some for fun during the US Open and started getting them more dialled. And in September for Lowers we made a couple more batches. So it’s been a while. He called me before the Australian Open and said he was going to ride one at Manly and sent me the details on the three or four best ones and asked for a new batch. He said if I nailed it he’d surf them at Snapper.
Do you feel any “morning-after remorse” now that he’s been seen back on Firewires and Chilli’s post-Snapper?
Haha – not at all. He has won contests and had a lot of great results on the Firewire boards. He’s got a relationship with Nev and I don’t think he takes that lightly. I think it’s just the exclusivity that he wanted to break free from. Chilli is my man."
Whole article's a good read, and shows you how much he knows of what current board shapes are working right now for pros and the average Joe.
