I'm working on a shockwave and i feel the best arms with good articulation might be either the Cybertron cybertron defense Red Alert arms or his repaint, universe 2.0 Countdown. OR! if anyone has CYBERTRON QUICKMIX/UNIVERSE 2.0 HEAVYLOAD that could work? OR! CYBERTRON CD SCATOORSHOT/UNIVERSE 2.0 OVERLOAD or DROPSHOT if anyone has a junker of him. please let me know! thanks!
