Long time lurker but one of my favorite accessories also but alas it doesn't work with the Armor Cap so I use a wooden clothespin to hold my cap and twist my 5 fin titanium tips that I have multiples of on various stems. Still trying to find solution for Omni and Vong tips thou. Armor caps work with my Hotshot, Apollo and Apollo 2 IH also.Another point that I forgot to mention. The Reload, everyone's favorite Dyna accessory from MadHeaters, is designed to be able to remove even a stubborn cap by having a lip around the magnet that you can slip the crimp into to grab the cap and pull it off. On the Armored cap the crimp is meatier and too big to slip under the lip so even this method of cap removal sadly fails.
