I have yet to hear of or see a broken Spleene in 4+ years, (except one that spent 3 days jammed in rocks being pounded by waves and then repaired later). I've owned and ridden many of them.
If you want a one board quiver the Rip shape is best, unless you want a directional - and then you should look at the Zone.
They have lots of sizes and shapes, and now 2 different categories: HiTech (all the bells and whistles) or the FunTech (less expensive and still nice, not as many choices).
Which size depends obviously depends on weight, kites, conditions, etc.
One thing though - the boards have very thin edges and doing beach grinds and hitting rocks will eventually damage the board (any board for that matter). Other than that I throw mine around without much concern and they hold up fine...I've ridden my 2007 Zone for 3 years, 150-200 sessions per year - no sign of breaking down. I also have some '07's Rip 28*, Door 54* & 64, an '08 39Session* and Rip34*...no sign of coming apart after Lots of abuse by me, friends, and students. I've never had a customer come back with a problem or not pleased. That's been another huge factor in my choice to handle these boards.
I am currently selling some of these (*) to "freshen" my quiver with '09, and '10's. Let me know if you're interested.
BTW...really nice pads on these boards...and the '09 pads/straps are the best so far.
