Good additions to an already solid kite.

The biggest change would be the tips/flex strut to improve turning. It would be interesting to see how much quicker it turns now.

I wont be upgrading my '20 rebel for this though. Maybe if they bring out an SLS next year.

Yeah I saw the same thread. If you continued reading it, the Duotone rep stated that the pulleys/sliders were only there for when the safety the activated to get extra bridle range and the limit stoppers on the bridle would stop the sliders having any effect when in the air.

I think the implication is that the designer has never incorporated pulleys to have an effect on the steering since it became 4 line and considers it to be a safety feature only. Slightly begs the question about why have a pulley on both frontlines if you have single line safety release but maybe it helps with relaunch as well?
