lets hope the rep system never comes back. +1 for everyone who never mentions it again.
Black is a bad color for woodland, it sticks out, but there are worse colors... banana yellow, candy apple red...
black ontop of woodland Camo looks OK, OD looks better, good looks and effectiveness are both debatable subjects, pick the one you like. Plan your loadout colors on what natural enviroment you will play in, camo doesn't matter so much in CQB.
if you get a 10 pack of star mags, you won't have anywhere to put them all, if you get a vest you wont have any mags to fill it with... what to do? I would personally suggest buying one or two real hicap mags (better ones than the UTGs)first, then the Vest, then the Star mags.
That way you'll have decent firepower even though you don't have much to carry, then when you get the vest you can put your hicaps +whatever other mags your UTG came with in it until you get the STar mags for the full fill. And you'll always have 2 good working hi quality full metal hicaps in your vest for when the s*** hits the fan and locaps wont do.
