Feels like min rate. Input chamber is cool. All 3 multibonder parts are used exactly twice per loop. Every arm finishes with a reset instruction.

My first solve (11R/480G) made 2 tringles with 2 single bonders. After solving for GI, I realised that there were more ways than tringles and made this instead. 

Arm 5 (below 7) saves this solve with its second swing to clear the multibonder.
