If it's the same as the 2013 LS quad then it's a seriously sick board.i used it mostly on a two weeks Maui trip last year. Have a review of it and the quarto 92 thruster somewhere on here
I sailed the 90 L Cube in South Africa for three weeks in January 2014. Unbelievable board, perfect for 4.2 and 4.7 for me (I'm around 84 kg). Super loose, lovely bottom turns, amazingly easy to redirect mid turn, can really carve a hard top turn (almost like a single fin), or slide out the fins with less back foot pressure.
I only used it with a 5.3 once and didn't enjoy myself - I prefer a bit more volume for slog and ride.
