I have a flat bottom board that works fine for me but have noticed most other boards have concave or channeled bottoms. Is this for better up wind ability or something else
My board also has heaps of flex were others are stiff. Is this for softer landings
Quad concave, with reverse V through the tail and quadruple steps for flex are the best boards period....
sh1t... i read your post quickly, and was expecting some cutting edge new design... had totally different picture in my mind... 
... reverse V - i was sure you were talking about some new channels design under the tail... damn fridays... 
Boards with a flat bottom and more flex are less responsive & have reduced pop (because of the flex)
channels in boards gives it more grip and drive off the waters surface depending on where the channels are, for example a Underground Styx which has a channel running all the way through the board and channels on the rail is going to have increased up wind ability and hold this also reduces the skippy feeling you get when putting in a edge in over powered situations (or when poping/ stopping quickly)
Another good example is the Cab Custom which has channels at the tip and tail of the board but a flatted out mid section for a skatey feel with equal weight distribution, this board is best ridden back foot heavy because of the amount of rocker the board holds.
Depending on what you want out of the board, where your riding Chop or flat water? waves? softer landings, more pop....
No you dont, you want a picklefork..... Massive pop, the fork gives grip by providing a release point through the tail and rides upwind like a truck at 5'11". pure cutting edge........
Does the lawn have any concave for extra moisture retention, or is it flat for more pop?
@Dave:
Does that board boost better than a small freestyle board? What size is it?
It's 5'11". This monster carries so much forward momentum when you send the kite, watch out!
