Have been riding this set up now for a couple of months and like it

Is an easy upgrade on most North Iron Heart style bars. (the older bars have a pin that needs pushing out, not screw out like newer models)
Am planning on adding a backup rope asap (any suggestions on this welcome?)
It took a few rides to become familiar with as I found it quite different.
Have found that I tend to ride with a little more kite/power with this set up than I have in the past.
Nothing bad, just different.
The rope slider is definitely better IMO if you are riding waves, unless you like to ride unhooked.
I like to ride/unhook on days when the wind and waves are constant and have kept my old harness for those rare days.
