Here's another option to using a snap shackle. I haven't seen one of these but wonder what you guys think about it.
What if you combined this with the Pro-Limit QR spreader bar? Do you think that would be better than combining a snap shackle along with an X2 QR trim loop?
The following is from Murrays.com website:
B&J Quick-Release Chicken Loop with Line
Bump & Jump's "breakaway" chicken loop allows you to ride "locked-in" when you want to be! Prevent unwanted unhooking of the chicken loop by simply slipping the plastic-coated end of the 8mm line under the chicken loop and into the open end of your spreader hook. You can do it with one hand --without looking-- easily! The kit includes 1m of 8mm Spectra line and is compatible with many sheeting systems and kite bar fairleads. Spreader/pad not included.
