Everything you need in life should fit in a VW van!
However, the 10.0 does have some disadvantages- you need some room to gybe. Luckily I found myself in the lead most of the races and didn't have to deal with much traffic. Anytime you get close to someone- disaster is likely to strike. I got taken out on the start of race 1 as TUR-92 decided to make some space between the pin end of the starting line and my 10m as I went for it, The result- we both went down. I was able to rally and finish in 4th. On the 7th race- I was arriving to the start line super early and knew about 10 seconds Id be over early without hesitating and letting the fleet roll me. Strategically, it made sense for me to draw over as many people over early as I could with a big lead already established. I went for it accelerating and drew another 3 sailors OCS with me. The result- they use their throw out while I've got a cushion to rest upon.
For me it's a no brainier- I pick the the equipment that's going to get me around the race course fastest whether its a 89cm board on the slalom course or a kite foil on the windward leeward course.
