Shook this out at a range/training event this past week. Some things I still want to do but setup overall is pretty much where I want it for now.
Eagle Aero w/ JTAC cummerbund
-Velcro One-wrap loops added to shoulder pads like Crye's carriers for hydration tube routing
-Heatshrink added to cummerbund handles to help strap up
-Added enhanced drag strap (connects to belt but weaves through vest)
-Velocity Systems MBAV front/back and Crye 11.5x6" side panels
-MSAP 6x6" side plates
Pouches (R->L as worn)
FirstSpear double mag pouch
Homemade triple mag insert, bungees on vest have S&S pull tabs
Homemade TQ keeper (3" of tubular webbing with bungee cord sewn in both ends)
Homemade IFAK pouch (copy of the Eagle GP pouch) w/ issued IFAK insert and IR cross
Crye 6x6 w/ homemade padding (1/4" closed cell foam cut to fit w/ velcro sewn on)
TCI MAST kit w/ Thales antenna
The only thing that bothers me is the TQ bungee solution. I'm a fan of protecting my TQs from the elements because I've seen a CAT that was covered in moon dust not secure properly, but I don't have a TQ pouch that I like. I've got a custom horizontal pouch that I don't like the integration of and the issued vertical TQ pouch that's kind of clumsy (but miles better than the nothing that was issued before), so this is the interim solution until I can come up with a pouch design I like.
(Un?)Fortunately my current gig is boring as shit so I don't need lots of stuff. This replaced my older UCP-pattern Eagle plate carrier which I had been wearing until recently because of garrison pattern Nazis.
