Sarge, did you lube the oring? The oring groove on the twisties are cut to the same dimensions as other e-series parts, and also share the same size oring (017). On a part that needs to be able to twist with relative ease, yet not come off unintentionally it can be hard to find a happy medium, but I find that when the oring is lubricated well it is easy enough to operate one handed if need be.
In regards to the twisty bodies not working on non-VME heads, the reason is that with a twisty body you have a very narrow window of engagement for the batteries (especially with the very short threading on e-series compatible threads). The very first twisty bodies were made (and sat on a shelf half-finished) long before the VMEs ever existed. They were two pieces to allow for different battery lengths and to compensate for the very short thread length on the e-series compatible lights. Since the M60 has a spring, this extra travel was not required for use with the VME head, and most people simply snugged the two pieces of the body together and used it as if it were one piece anyway.
The old twisty bodies (which I believe there are still a few of left on JSBurly's) will work with regular e-series heads (by screwing the top piece firmly into the e-head and twisting on/off at the joint between the two body pieces), whereas the new ones will only work with the VME.
I do have a website now (
www.valiantconcepts.com) and I'm hoping to get these twisty bodies on there soon (with a bunch of pictures), but my website guy has been slacking off. It's so hard to find good help nowadays
Now about the clicky bodies not matching the VME heads perfectly, the anodizer messed them up and had to redo them, which gave them more of a matte finish. I decided to put them up at a discounted price (they cost more to produce than the twisty bodies, especially once you add the tailcap) with the disclaimer that they do not match perfectly, for those who still wanted one. If these ever sell out, the next batch will match the heads properly and likely cost a few dollars more apiece.
