I weigh 130 lbs. and have paddled both the 41 and 44.  The 41 is a little flushy in holes with my weight.  If you want it just to do flatwater stuff go for the 41, but if you want to have fun playing in holes without flushing go for the 44.  Definately try it out, you'll have a lot of fun in it.

Paddle hard,
Nick
