Thanks All - appreciate the advice. Managed to get a great deal on a 9' Redwood Paddle board, (Phenix LTD Wood). My flat water SUP is a 9'8" Fanatic Fly and with me being a long time surfer i'm fairly (!) confident this should be a decent size to last me a while. I have made the mistake before of going too small on my normal surfboards but feel like 9' should be a decent size. The swell never gets too big here anyway.
Appreciate all of your advice. Will follow up on how bad, or good, this decision was in due course
