I'm well-experienced with dual-line stunt kites, and am going to buy a Revolution quad. In doing research, I'd like a better understanding of the differences I would experience between the Revolution EXP on the low-end, and the B-Series on the high-end. I'm not really worried about the price difference, and I'd like to own a kite that can keep up as my skills continue to improve. But I also don't want to waste money on a more expensive kite like the B-series or New York Minute if the flight characteristics are only marginally different than the EXP. So in short, what makes the B-series a better kite than the EXP? Also, does the mid-vent have the widest wind range?
