Been watching this thread for a couple of days
It is my recollection that the bridles were left off the 2004 rules by error
aluminum poles will require bridles due the stress loads
I think Carbon poles would be fine with a D ring when running down wind in the higher wind conditions but I would have concerns as to the loading when beam reaching. Tapered poles which our rules do not allow for are can be built with D rings. I will check with a couple of the pole manufacturers and get there views on the D rings for carbon poles
Trigger ends were not allowed due to the fact they are not retrofitable to the old poles.
