I've had this dilemma for 2+ years now.
I like width for stability between waves and confidence when sitting in a pack rather than shaking / shuddering with bent knee's or falling off which just sucks.
In saying that, in good waves, the width is so noticeable for anyone with a surfing background, they labour and the lack of speed compared to a 27-29 inch board takes the buzz out of the experience.
Similar to riding a longboard then jumping on a shortboard. You gain something (early take off / set up) but you lose sensation and critical moments.
I decided to stick with the casual approach with 32' wide boards (Fanatic All Wave & Star-board Wide Point) however to this day I miss the down the line speed of narrow boards but enjoy not looking like a crabby kook wobbling about and falling off in the line-up and given that we only spend 5% on a wave and 95% balancing, the width and comfort outweighs the speed factor IMO.
