I carried a Stilleto for most of the last 2 or 3 years. The shape in pocket and the high only tailcap for emergency use with the multi mode side switch for admin use is just perfect. I sold it when I got a Cloud MCH 18350 on the day it launched. Id wanted a super high candela light for awhile based on all the current influencer marketing. High candela lights are not a fad or gimmick, but for my life and my pockets, after a month with the Cloud, I traded it for a Stilleto Pro and haven't looked back. The flat shape and separate switch for admin use is just far too perfect.
I do have Streamlight HLXs on my rifles and an old 2LX that I would keep as a backup for backpacking once (if) the Stilleto runs out, but 99/100 days, the Stilleto and Stilleto Pro are perfect.
The aforementioned Streamlight 1L-AA with the CR123 or AA is an amazing backup/throwaway/stash light. I had one of those too but gave it to my little brother when his Klarus started smoking.
