The ThruNite T10 is a bit larger and heavier, but it is also significantly lighter than the old fashioned Fenix. It also makes a very high-quality and sophisticated look - I'm on Titan. Therefore, I was also the hefty additional cost aluminum version almost matter.
What I think does not fit the T10, is the clip. If he's screwed, not only the clip itself is on fairly high, but the pan-head screws. It looks cheap, that sophisticated look is gone, which is why the clip stays away with me.
