There is a difference in regards to the 100 vs the 200lm. It throws better and overall its brighter, but is ot visually 100% brighter due to how our eyes see things on a a logarithmic scale. There are other threads that can explain that better than I. Overall, it depends on your needs. I think the trade off for added runtime with the 20/100 is nice. But, as I mentioned a moment ago, I have more than one Raw and each one has a different LE (light emitter).
As for the Fenix L0D on 10440's, I need to recharge the batteries, but the Raw's 100lm were brighter than the L0D's on 10440's on high. IIRC, with fresh batteries, the L0D will be brighter on high versus the Raw 100, but about the same as the Raw 200. Also, both the L0D on high and the Raw at 200 will have about the same runtime.
Lastly, the NS polishes up very nicely! I don't have an Al model to compare it to, but I also like my Ti. The weight difference between the NS, Al, or Ti are noticeable, with the NS being the heaviest. The NS looks and feels very jewel-like. I haven't seen the Al in person, but I would assume it looks very nice and being bare, can be polished nicely (there are posts on that, too). The Ti is nice; maybe a little over the top. Anyway you go, you will be happy...and probably will end up getting the model you didn't originally get...just out of curiosity.
Good luck! :twothumbs
