Ok then,
These arrived this week from Pig iron, a selection of master/armature casts for the next system troopers release:



Started to work the armature into a dual welding pose, though may take the arms off the static pose and add to one of the more dynamic bodies.
Also ordered some Spugs from Paul Reid

Great proxy Covenant: a little big for grunts but work well besides and the jumppack spugs: drones all the way! The website pics don't do them justice, it was Monkey Fighters paintjob that sold me on them.
More to follow, currently looking at as I said CSO peacekeeper arms + pinned a few so will probably sculpt some full arms too.
