I only really need two for the environments I play in,ie indoors cqb and woodland
As such I run a black police/SAS type set up for cqb and DPM for the woods......I know MTP is cooler but its nowhere near as useful as dfpm in the woods imo
Weapons wise,a ics SIG 551 Mrs lb AEG and a we scar gbb plus a trusty we SIG 226 in a serpa drop leg......seems to cover most bases
