At first when i saw this range of boards called "long grain" and the video advertising those SUP, i really thought than TC give up surfing.
Finally, i agree what Area said for all points and for the most of all " a key turning point" in longboardSUP.
I said TC give up surfing, i hope he 'll apoligise me for this because i just do understand now the weight of his board has been specially done to crank the board on rail and outline as TC been surfing his whole life.
The day before i surfed some 2,3' perfect hollow wave with a laird 10' which is more single fin rocking board rather than a curved outline 4finned of the Long grain but i would like to have a go to carve on rail down the bottom then burst the exit door feet first with the help of inertia of the long grain board weight and a bit of the spoon ridged

next time..
