Dual Deploy Question: Redundant Charges? Or Redundant EMatches?

[Banzai88]

I'm now in the camp that has two flight computers (each on its own battery), with one charge per function (deploy drogue, deploy main), and each with its own ematch. So, the only way it could fail is if both computers simultaneously fail, or both ematches fail, with the same charge.

After a season of bad Chinese ematches (the orange wire ones that everyone swears by), I'm in the same camp as you, with the addition that I'll only ever again launch with mjg firewire ematches.
