I sold my M6 immediately when I heard they were coming out with the invictus in 2008. LOL. It seemed like it had no place in a world where there was a 6.9", 8oz, 1-1.6" diameter, 400 lumem, output adjustable, led flashlight. Again LOL. I have a Novatac 120T for my single cell light, I wish it had the tailcap of a surefire where either by pushing or screwing in it would go from a low setting to the highest setting but besides that it is great. I have a Wolf Eyes Storm for my photon cannon, it was rated at 580 lumens and I thought the 400 lumen rating on the Surefire would have put it in competition. It is way to fat and heavy for my taste, and I hate its switch, but works well.
I have been dying to upgrade and by some new flashlights. I wouldnt have cared if the 2008 Invictus was $500-$600, I would have bought it. A new single cell light from surefire that took things up to the next level would have been bought immediatley. For personal use IMO Surefire has not come out with a noteworthy upgrade in the last 2 years. I had a L2 3-4 years ago that was 100 lumen. Now they are 120 lumen! Who cares. The new invictus at over 9" and almost 13oz makes me wish I had not sold my M6 at the beginning of this incompetent sleigh ride. I don't mean to be overly negetive but I am in a 2 year long fit of dissapointment topped off by the irritiation of my dream flashlight being replaced (if it ever comes out) by a 40% longer, 50% heavier, 13% dimmer stupid version of itself.
Just my 2 cents about what Surefire is doing.
