Hi Jeremy,
long time no see! Hope you're going well, we'll catch up one day..........

Heard some good stuff about Infinity (from California) last December, so I contacted Matt, the local distributor, and he put me on to a guy who had the perfect 10-footer (to complement my 8'7" JL Kwad, moved my 11' CBC on) for me to demo, 27" wide, 122 litres volume, the New Deal. Met him down the river, East Freo. Carbon, very lightweight, great stability for a narrow board, and the construction has had nothing but rave reviews.
Matt had one left, no more of that model worldwide till March this year. They're pretty pricey, but we're talking about the top of the wazza here, thought what the hell, I'll keep it for years, so lashed out and bought it! So glad I did, beautiful board, best I've ever owned, carbon, lightweight (7 kgs). Just waiting for some better waves..............

For a better surfing sup set-up for you, what about around a foot shorter than your 9'6" Naish? Matt has an 8'5" x 30" B-Line (114.5 litres), or if you prefer a fuller nose, he's got the RNB in the same length, wider with more volume (31", 133.5 litres).
nextlevelsup.com.au/products/infinity-b-lineThe New Deal's are coming in March I think (if you can wait that long), check with Matt. Another one for you could be the 9' x 28" (104 litres). Currently Sold Out according to Matt's website.
Good luck with the search!
All the best
Mike
