this could be the right board - I'd say it just depends on your weight and paddle power. I'm 5'11, 80kgs and intermediate+ I'd say and just bought the 6'2. obvioulsy most of the waves we ever get are waist to head high but I'm hoping not to feel like I need a different board when it gets overhead.
i spent a bit of time researching loads of options before I got it. I surf a 6'8 aloha quikshift which has been awesome for me over the past 2 years, but hoping the squash on this might help with better topturns. that's the hope anyway - now need some waves. I had it out in fair sized swell last weekend but it was very lumpy/onshore and whilst it paddled fine, it wasn't the greatest conditions for working out if it's going to help me do what I want yet. However I reckon the 6'2 was the right size for me and my current paddle fitness (good)
the only other thing i think is important - never had a webber before - but a few people have mentioned the special concave he puts on his boards. maybe it's a marmite thing but i've heard people get very enthused about the shape.
