My hotend stopped heating, and taking it apart revealed that one of the arms had sheared off. Not sure how as it shouldn't have been moving relative to the heater block, so shouldn't have fatigued. Would heat have played a part?
The one I have is 6.8 ohms, 4.8 mm in diameter and 15 mm in length. I have been unable to find one with this spec that supports the required temperature range and that can handle 3w. If it was possible to find one with a lower resistance to output more power, would that be a good idea?
Just out of curiosity, does anyone recognise the type of my broken one? It has a porous ceramic like texture.

I am also toying with the idea of scrapping the existing hotend and getting an all metal (E3D) one.but have reservations as my peek based one has been printing fine, with no jams at all. I am only printing PLA at the moment.
