Just wanted to hop in with a follow-up to Paul's posts from March. I've finally put sticks on the back of my zen (none of my 1.5s have 'em), a Flying Smiles french bridle on the front (with some minor tweaking by Paul) and a hybrid frame (2wrap center, race outers on the LE, Zen verticals).
My Zen was one of the first off the production line back in, what, 2010? It's never the first kite I pull out in light winds; I'd rather fly an SUL B2 and have fun on my own if there's not enough wind for team flying with 1.5's.
With the tweaks and tuning, Sunday was the most fun I'd ever had with a Zen. The kite tracked, turned, and stayed loaded in a way it never has before.
