Sockman, my mindset is pretty much like yours. It takes away some of the enjoyment of using a light if you're worrying about using your batteries up all the time. I'm far from a tree hugger, but I'd still like to keep from throwing more batteries than I have to into landfills when I have another option available. I like being able to use whatever battery pack fits my needs on any given day.
Don't get me wrong here, I'm not signing up to upgrade my LSH-P to an Arc4 if Peter decides to make the 2AA pack, because I'm still not willing to spend $180 on a flashlight. I got my LSH-P for $125 new and that was only possible after rational thought left my head. I need a lottery win, a good sale or a used model to get me to upgrade because I'm pretty happy with my LS just as it is.
There's no reason that the 2AA pack needs to be a losing proposition. A poll to test for interest is fine, but the real way to do it is to make as many as you need. If you need to make and sell X battery tubes at Y dollars to make a profit, open a pre-order and tell everyone that they won't be made until the requirements are met. Then you get enough orders, manufacture 'em, bill 'em, ship 'em and you're done - if people don't put their money where their mouth is, then no 2AA pack for you! /ubbthreads/images/graemlins/smile.gif
