6p or 6px?



So I am heading to LL Bean today to return an old jacket. With my store credit I plan on buying a Surefire. What would you guys recommend? The metal 6P or the Nitrolon 6PX? I plan on modding it a bit down the road with the Malkoff business and all of that so should I stick with the metal 6P or are those a bit dated by now? Im just getting started in the whole flashlight world so I figure its one that I should probably have, considering it seems everyone and their mother on here has a bunch of them. Thanks for your input!
