I have a couple of Dorcy AAAs. I like them. They are bright, but the beam has a lot of rings. The beam on both my Ultra-Gs is brighter & very smooth. I keep a Dorcy AAA in my car for reading driving directions at night. I don't like it on my keychain for edc. It just feels clunky. I'm specifically looking at keychain lights. The Ultra-G is at the extreme top end of what I can accept in size. I've never seen or held any of the ARC AA or AAA flashlights so I was trying to see how they compare in beam & size to something I do have. I have not purchased an AA or AAA ARC because I did not like the twisty on my LS, but with the Ultra-G I discovered I like the twisty on the front of the light. I am planning on purchasing either a AA or AAA ARC at some point, but want to see how big they are.
