Rplying to John Slade's reply:

I like your plan.  If 1 pump fails after achieving cruise altitude (done
with climbing), then you will be well within the "'Nuckols" envelope of "it
isn't critical - you can complete your flight" (or do precautionary landing
at a convenient place, as we were taught in the AF).

I'm seriously considering 1 or 2 esp's, like you.
