Hi,
Just traded my JP single thruster 83 (2011) for a Tabou Pocket 80l (2013)
I'm 80kg, this is my small board for my 5m and under.
I ride mostly in rough onshore conditions and find the Tabou to be less bouncy in the nasty stuff, better on my knees.
The JP is faster and not as loose, more bite in the turns.
Tabou better foot pads/straps
Tabou is cheaper
I know at least 6 sailors who have changed from JP (Single thruster, Quad, FSW) to Tabou (Pocket, 3S) in the last year
