Its crazy how sometimes one thing ties it all together.
Frankly I think most Destro figures would look better with those pads.
And I might try v3 (which is the same as v1 colors) with those pads at some point. v3 just to make another figure we don't have in modern.
I mean the only O-Ring Destro's we don't have are...
Destro [v003a] --- Super Wide Lapels
Destro [v004a] --- Armor Tech
Destro [v008a] --- JvsC (red)
Destro [v009a] --- JvsC (blue II)
Destro [v010a] --- Spy Troops
Destro [v011a] --- VvsV
Destro [v013a] --- M.A.R.S. Invades
Frankly v9 is similar to v7.
v6 and v12 are similar to v5 (12 has white gloves but otherwise the same)
And long ago I made a version of the M.A.R.S. Invades...

So might knock that easy v3 out.
