We all say we will only have one board when we start

Then all of a sudden you see someone on a flat water race board going really fast and a little voice says "hey wouldn't that be kinda fun"
The AllWave is an awesome little board and the other one you might care to look at is a Starboard Wide Point, both are relatively short, fat and easy to paddle.
The secret with these types of boards is go the size down from what you would usually use. I am 5-8 and a variable amount of fat depending on time of year. I use a 9-5 Starboard Wide Point and would easily feel as comfortable on the 8-10, the difference in volume between the 9-5 and the 8-10 is approx 4 litres.
