[Unanswered]  Heaviest legal combo per gen.

Hey guys!
I know that the heaviest Burst Combo is probably level chip Perfect Phoenix .00Wall/Sting .Charge 
But, what are the heaviest BSB and MFB combos?
I was thinking about something like MF-H Diablo Whatever GB145MB for MFB, but don't know anything about BSB/HMS customizations, so don't have a point to start

Can anyone help me?
Plastic: I have no clue. MFB: MF-H Diablo Kerbecs BD145MB. Burst: Perfect Phoenix Blitz, Sting, Hurricane (not sure which one's heaviest) Charge
