Swapping a Speed Pemi for the Bad Boy?

I've got a speed Pemi on the calendar for Saturday, 8/20 (PR for a counter-clockwise loop of the Pemigewasset Wilderness w/out tagging West Bond, North Twin or Galehead is 10:55).  Various aches and pains and the upcoming D2R2 and RTTTOV are suggesting the plans change.  If so, the other option is to hit Mt. Washington which I need in August, Oct & Nov to cross of the grid list.  Either way, unless we're dumped on with rain, it'll be one or the other.... or Adams Slide ... or something else....
