I traded up from a BIC Dura Tech 10'4" to the Slingshot Crossbreed 11" almost two years ago and have been very happy I did. I find the board is lighter, easier to maneuver and faster on flat water.
The board seems faster on flat water; it turns easier and overall is a better performance board.
At times I wish I would have gone bigger (12') because it doesn't track well on windy days.
I use it for exercise and touring on lakes.
