My current bag for the BOB is based around a Karrimor SF Predator Tecmac 50 in coyote Tan.

Additional pouches are 2 Karrimor SF PLCE compatible side pouches and a Flyye Army Combat Versatile Shoulder Accessories Bag MOLLE Cordura Coyote Brown which attaches to the Molle Palls Webbing on the back of the Tecmac 50

A PLCE side pouch yoke will be carried to allow side pouches to become a lightweight Ruck as well.

The Tecmac 50 doesn't have a padded waist belt as it is really designed to be use with a LBE kit such as PLCE webbing.

A PLCE webbing consists;

Main Yoke [NSN 8465-99-132-1560]
Quick-release Belt
Hip Pad/Hippo Pad
2 x Double Ammo Pouch [NSN 8465-99-132-1557]
1 x Utility Pouch (Pouch, Utility, DPM, IRR) [NSN 8465-99-132-1558]
Respirator Pouch (Haversack, Respirator, DPM, IRR) [NSN 8465-99-132-1559]

balancing out the load would 20-25lbs on the PLCE webbing and 30-40lbs on the Karrimor Predator when fully loaded. this setup is very modular as well. This will all de-construct to fit is a bright yellow BOB BOB trailer drybag

The Main problem with the ALICE is that when loaded you can't really stand up too straight without the pack wanting to pull you over on your back.
