Hi!
My first kites were Helix and Cult, latest years RPM's, and i 've had and have tried RRD's, Ozone's, Wainman, Naish Park + +.
No Kite I've tried comes even with the Zigmas when it comes to handing gusty conditions, when sailing straight forward. The stiff frame, good depower and outline of the kites makes them so easy to handle. However jumping with them in gusty conditions can result in overflying if there is a sudden lull. ( my personal experience)
I swithched from Zigmas due to the "stiff" feeling you get from the kites, and didn't like the park for the same reason. It's like they are to much on/off for my taste. As for wave riding I feel the RPM's are way superior with it's "drifting" capabilities,and provide a much "softer" feel. 12m and 8m RPM's has had me covered from 11 to 40 knots both on a TT and Surfboard.
If you like the way Zigmas fly and want to try somthing new i think WH is a pretty good choice.
Extremly friendly kite with great depower and coolest graphics on the water.
Myself i'm going Banddit 5 myself this year
good luck with the choice
