Hi Phil, for performance in the beachies and also fast, powerful waves, I would pick the 8'11. I am bit lighter at 70kg, but for 80kg rider, the 8'11 should be plenty stable enough. Both are 28.5 wide, but the 9'6 at 135L (8'11 is 126L) is not as much of a step down from the high volume Mana, and a more versatile board. Probably comes down to thruster vs quad preference, and if he would be using much in flat water.

Thanks Guys

Appreciate your input
