The 06 bridles were strong on the outside sleeving but the inner cord was weak. I also broke both of mine just a week ago (a bird hit one and it broke!). Considering a sandy pulley has been riding on them for over a year it's no surprise they finally broke.

Here's how you fix em quickly with Q line:

Cut out the large V sections that the pulley rides on leaving about 6 inches on the ends where the first vertical bridle attaches to this line. Put a few figure 8 knots there one inch apart (for adjustments if necessary later).

Cut two pieces of Q line and tie loops in each end (they should be 178 inches long for the 16, or 143 inches long for the 12 after the loops are in.. double check against old bridle to be safe). Loop them around the knots in the remainder of the bridle, and the other end to the pigtail on the tip and you are all set.

Removable bridle sections which can easily be replaced without having to tie all of the other knots too.

I can show you if you need pics.
