Familiarity: I've used it several times
Stiff enough to charge, but not too stiff to cruise. Great lateral support with a nice smooth flex. I can't speak to park performance...
Boa closure? HELL YES! Best thing to happen to footwear since velcro! Double dials, one for the forefoot, one for the cuff. Simple dial turn to fine tune fit with perfectly distributed pressure. But be ready - if you have laces now and you buy these it will ruin you forever.
I'm riding them right out of the box and they feel great - a little customization of the liner would make them heavenly.
