So having tested the loadout in the field:
Knee and elbow pads: Can't wear them over clothing as it will look wrong, my current pads are just not comfortable worn underneath. I may have to think of a better solution
Sten: Frickin awesome at mowing down groups of enemy as they advance, may try some heavier ammo next time to get a bit more range and punch through foliage (was using .25's). Battery useage is high, I have a hunch that the Burst wizard may be sucking up battery power so may ditch it for outdoors.
Ammo pouches\mags: May have to sew in dividers so that mags can be kept organised to determine which are full/empty, or may just number them on the ends. May have to get more mags as when the shit hits the fan and serious suppression fire is needed, 6 mags really don't last long.
Comfort: Denim battledress is really comfortable. Denison smock is great for when it rains. Pocket space is a bit on the ridiculous side, hard part was remembering what was in each pocket. The fact that a MK23 Socom fits completely in an inside pocket of the denison (silencer off) says a lot.
Overall weight of the gear is rather high, it gives a good workout but it's not uncomfortable.
Oh and on another note, I have a Steel helmet for my loadout due to arrive Wed/Thurs A bit more weight but who cares, its a frickin WW2 airbourne helmet
