I am loving the new 3mm peg system on the NEST/ HFTD line. Its so simplictic, but effective. Its a nice touch for giving figures that don't come with any/much accessories a little bit of extra fire-power I've been scouring through all the figures i recently got to see who is compatible with it, after i got a recon ironhide, and started messing around with the insane level of weaponary that came with him. so far Ive found - Brakedown - can clip stuff to the underside of his hands Brawn - Loads of places that weapons can be clipped to him (looks great with recon ironhides guns) Hupcap - the exhaust pipes on his arms Mindwipe - his legs Breacher - few spots on him. Seaspray - the silver 'ladders' on his shoulders in robot mode. Am I missing anyone?
