I can sympathize with someone feeling that a light is too small for them. It's their opinion after all, and a highly personal thing... for items that essentially become attached to a specific person, or maybe associated with or accompany them is the better term, they become personal objects, specific to that particular user... and one size most definitely does NOT fit all! /ubbthreads/images/graemlins/ooo.gif
Among other things, I'd say watches, knives, and flashlights all fit into this category.
Now for my OWN personal opinion on the matter, I feel that a light becomes too small when I can't easily grip and activate it with one hand. I feel very strongly about this! But that said, I'm not going to try to claim that's the definitive test for everyone.
For me, one consequence of my minimum size standard is that I don't like to put Z52 (the twisty) tailcaps on an E1E body, because my fingers can't reach far enough back to perform the twist action without seriously loosening my grip on the light. I use Z57 clickies on pretty much all my E1E bodies. However, an E2E body, and even one of balrog's BE1.5 bodies, are long enough that I can easily use the twisty with those! I'm sure everyone has their own standards in these things. /ubbthreads/images/graemlins/smile.gif
Okay, for all that rambling, I guess my point is that I can totally understand how Al might find a certain light too small for his tastes, simply because of the physical size of the thing, not the compromises.
