Forgeworld Reaper

Just ordered two Forge World reapers, mainly for the haywire, but I noticed they are the only unit in the army that can cause pinning checks... Has anyone had any success with Wych's and reaper combo? On paper it looks like they work well together, not sure though because I don't like proxy and wont play the models til they are painted.

I have one for inclusion in a Ld Shenanigan army. I'm more stoked about cheap Torment Launchers and Night Shields than the Pinning.

Pinning is never something to rely on. I like the reaper for the haywire but more so for the ap 4 large blast.
