I have the Cryos II and it has 6 trit slots around the head. I have installed trits before with Norland 61 in a Ronac Standoff tailcap. The trouble I am having is the slots are too shallow in the Cryos. I found something about someone using a dremel to go a little deeper in the slots but that seems like a dangerous plan. Besides I looked everywhere before posting this to try to find that and I can't find it. I would be severely irritated to say the least if I messed up that Cryos. Any ideas?
