As an update, after much discussion (and some humps) my bud decided on going with a modified chest rig/vest kind of set up for the radios. He is currently trying out Jay Jay's patrol yoke, in conjunction with the belt kit. He will run at least one 152, map, compass, NB, and "AM" on the vest.
He is on hurricane relief duty right now with this set up. It allows him to drop combat kit, for humanitarian missions, and still have comms and his "office". Such are the realities of the modern soldier.
His ruck currently sits at approx. 40 lbs, with another 20lbs of belt kit. So 60 lbs all up, for a soldier just under 200 lbs.
For me, the ruck is approx. 35 lbs, with 15 lbs of belt kit. 50 lbs all up for a "G" at 160.
As we have been discussing here, I think these are very good figures of merit.
