RSI has had their Sheet Cleat System out for some time. It allows a rider to be in trim loop and "lock in" at any point on the range of the bar without pulling a strap. Great for tricks and comfortable cruising. However, I've heard mixed reviews on how well the Sheet Cleat actually performs.
Now Flysurfer has just come out with what appears to be the next generation of this type of device. They call it their "Pressure Free Depower System". The Flysurfer design features a pulley instead of a cleat and may be an improvement in this type of device.
Please reply if you have experience or info on these or other similar products.
Note: For some reason, it seems Flysurfer has today removed their new "Pressure Free Depower System" from their USA Website. Perhaps it is back online by now or still showing on their Euro-site.

Thanks for any insight on this subject. I would like to combine the best of these devices with the best shackle/quick release system and use them in my regular set-up.
