The only reason it isn't popular is because hardly anyone sees it.When you think of how many cable parks their is it explains a lot they are only for wake parks pretty much, they are hard to land flips with out a direct drive cable system which the operator can adjust speeds at the drop of a hat. Sesitec 2.0's are the best systems to learn on rather than a full system, air tricks - raleys are piss easy on full systems with the speeds and how the cable system arcs.
The bindings that they run are shit, it is better just to run a soft park boot on and something with 14 din as you would want to be running them at 12 all the time. Learnt that from experience from blown $2k worth of slalom bindings and stereos own shitty full frame boots. Plus you can use them for kite skiing out on the water as you can run up to your sticks with the kite and just kick and kick out when you come back in shore to land your kite after your session
They are a real blast they feel like skiing in powder, would highly recommend them if you have the cash to put an alpine set up on them. Plus you can go twice as high as any Wakeboarder
Overall it improves your skiing greatly and is always a blast, but you will always be mobbed by Wakeboarders where ever you go.
