Good post Kim.
I have seen many ferrules that have snapped off of the carbon shafts with the T design. Some are solid and some are hollowed out. These ferules look like juma or a similar material and anywhere from .250-1.00" long. A side drop on a hard floor and they snap off at the end of the carbon tube. The wood tendon does greatly reduce this situation. I was going to show a picture of the snapped off ferrule I had laying around but can not find it now.
