Shook's mesh rev kites are popular because they are way lighter in weight (no heavy mesh material) for the same purchased wind range compared to any other Rev products. Granted you paid more, but it's almost like getting two kites in one. It will fly in lower winds and really big turbulent gusts equally well. Changing out the frames gets you a 25 or 30 mph spread of usable wind ranges. Buying two "Pros" or one Shook Mesh? I've flown the full weave (100%) in 8 and steady winds over 40 mph with the same green race frame. If I switched to my B-series Pros I'd have had three of 'em out instead of just one.
Had I purchased my Shook first, I wouldn't own my full vent or any other vent.
