I'm going to be painfully honest here... The "redesign" involved in both the B-Series and B2 were minimal, ultimately minor changes to the panel layout and curve of the leading edge... Sure it helped performance some, but I was never allowed much leeway in the end result other than aesthetics, Rev is a "kite company" and with all kite companies, most of their product entries are to stimulate that next wave of sales, not toward a "mean reason" on its own, takes "everyday pilots" to go there - it's the very reason I'm where I am today, to be able to actually apply all of the refinements we've developed and learned about.
And this too is valid! But we'll leave it to other companies to produce these "fun" kites that don't have any true sport application or that don't further the true evolution of our pastime... To be enjoyed by a quite a few for sure, but that just ain't my bag - that's why you'll be able to trust everything we produce to be at a certain level, in every way.
