The Typhoon (and its cousin the Night-Ops Gladius) were very well respected. See
here for a review of the original Gladius.
That new Handheld X-treme series looks interesting. Wish there were more details on the website, but it looks like it's an update of the Typhoon/Gladius with a few extra features and new cell configurations. I'm guessing the tailcap now has two additional positions - max output constant on
twothumbs) and SOS - and as long as the dimming mode still has memory, I'm all for the changes. An updated Typhoon minus the finger grips and powered by an 18650 (presumably) would be very nice. And, I like that the rechargeable Arcturus is only $10 more than the 2x123 model.
