hi MountainKing,
SashiX has the Alu 2012 model and he could comment in detail on his sample (tint, brightness). runtime of the Alu is miniminimally higher (~80mins vs. ~74mins, and i am still running runtime tests) but in terms of light output, hotspot size (as seen in the table and animated gifs), the SS 2012 is an outperformer and i am highly surprised. I had the SS 2011 and it was extremely greenish and with low light output. So there is now a boost in improvement in the SS 2012. Amazing output, especially its integral brightness, and tint on low-mode is less greenish than it used to be. On high-mode the tint is slightly greenish and comparable to the typical greenishness of the iTP A3 XP-G R5 which everybody loves; the Klarus MiX6 has a much better tint, no doubt. I am running the Worm SS head on the Worm Alu body (to save weight) but i could run it also on my iTP A3 body (to save weight).
So it's a little difficult to decide between SS and Alu. It depends on the purpose, really. If you need a great great AAA torch, then better just go with the Tank E09 (i dont mind the low-frecuency PWM. i find it cool!) because it has all versatility and safe operation with a total of 6 brightness levels (3x Eneloops, 3x Protected 10440's). And the head is supereasy to twist. If weight matters to you a lot (the Klarus MiX6 Ti weighs 12grams!), then you should have a spare body (iTP, Olight, Worm Alu, E09) .. also in order to queen-shelf the shiny SS body.
I wont recommend the Worm SS as torch if it has to be your ONLY 1x AAA torch for a flashaholic. If a flashaholic plans to own just 1 torch (of the 1x AAA form factor), then i will always recommend the Tank E09. (or the iTP A3, or even the Fenix LD01, for those who dont want to fiddle with the E09's insulation issue new out of the box). However, in any other case (non-flashaholic, or flashaholics with 1 other AAA-sized torch), i would full-heartedly recommend the Worm. My personal nods goes to the Worm SS. The weight is still acceptable (compare with Preon Revo SS, Rofis ER10 SS, Klarus Mi10 SS, Fenix LD01 SS, and any other 1xAAA SS model), and personally i can just swap the SS head onto my Alu body.
btw, the review isnt 100% done yet. Once it is, i will change the thread title. SashiX wanted to contribute a set of beamshots, and i wanted to run a few more runtimes in low mode (SS).
The SS is more like a piece of jewelry (with the best output on Eneloops one could imagine, integralwise), and the Alu is thrower -- not too suitable for reading books ;). too bright, too tight hotspot, too intense.
Maybe SashiX can share more of his experiences?! :)
