Hi Dan,
IMHO don't go with the Tiki board. The reason I say this is because I've just done loads of research into buying a decent new custom to use instead of my epoxy pop out mini mal and I found
http://www.surfedout.com down in Braunton in north Devon (just opposite the Tiki shop).
I went to the Tiki shop to buy a Sumo and even tested it, the guys were not exactly helpful (bordering on "couldn't be bothered") but also the board didn't really get me going, it didn't have that wow factor, it felt a bit slow and sluggish and not very exciting.
Then I went over to see this other shop, and the difference in service and quality was astonishing. I had a chat with Glenn (the owner) He was really helpful and passionate about his stock, He asked questions to get the info He needed to know to find out what I wanted out of a new board and my surfing, then He
insisted not begrudgingly offered a test board to prove his point! The board I tested was a Nigel Semmens B52 hybrid, very similar to the Sumo on paper but very different in the water, it went like lightning from the take off and turned on a dime!
All in all his knowledge, service and attitude towards me was a league above what you normally get these days and I've ordered a brand new B52 with slightly different dimensions based on what Glenn and Nigel recommended (He also passed me the phone to talk to Nigel about the board).
In short, if you go to Tiki they'll sell you a board and take your money...
If you go to Surfed Out, you'll get a board that will suit you down to the ground and service you will be amazed with!
Oh, and trust me, I'm just a happy customer not a tout for his business!
