30" lines . Are you KIDDING ME!! Last week after 2 years I finally had 2 good days on 50' lines with a sul. Dang it, dang it, dang it now I gotta go short line my Widowmaker.
The B2 is a 72 inch leading edge kite. Much smaller than a 1.5 sized sail. It's the quad version of of a Prism Micron. Very fast, twitchy and fun. Not for beginners. John makes it look easy, it's not. Cool kite, not a second kite more like a 5th.
The B is light years better than the exp imho.
I have a couple of sets and the exp. I LOVE my B-series.
With that wind range, I'd definitely get a standard. 👍
