Some shooters use dental bands, and as I understand it, the new ones have a retention system. But they'll never be in my quiver again! All it took was the look of that huge 8-pt rack bouncing away from me to make me swear off mechanicals for good.
I use Montecs and Snuffers exclusively. They are solid with out any removable parts and they re-sharpen easily. As long as you do your job, they'll do their job.
No soapbox...just my experience.
