My load out changes have involved many factors including the effectiveness of my camo and equipment, my knowledge, income, and my perception.
When I started I thought black was the most awesome color ever. Then I played in it. I was hotter than everyone else and my gear always looked dirty. The rare occasion we played night games my silhouette stood out.
So I got a set of cheap woodland BDUs from a local surplus store. I have used those for years with various knee pads, bets, holsters etc. but I have never had the funds to buy a nice "loadout".
Now my next big airsoft related purchase will be a complete set of digital camo bdus with a MOLLE style vest, mag holders, pistol holder, dump pouch and the like. I have a second g3 on the way and my plan is to modify the easily interchangeable stock and grip along with my loadout so I can play a regular rifleman role for one game, a Designated Marksman the next, and a support role the next. Both my gear and my gun will be modular and the digital camo seems to be effective in almost any environment.
And that kind of sums me up right there. I never have the inclination to specialize in any one thing for to long, but I tend to catch on very quickly to new things. Jack of all trades master on none...but I will exploit my versatility whenever I get the chance
