From my experience, with a W/N, the extra group isn't worth it. I can do 34 in 40-45 seconds on an average spawn, getting the extra 6 adds about 7-9 seconds, so you're gaining about 15% more kills but using 18% more time. When you're doing hundreds of runs per weekend (I think I did about 300 this weekend), that small difference will add up. On some runs, sure, it's worth it to go grab the extra group if you're already near the entrance again, but I certainly don't think it's worth it every run.
Also, even with picking up drops, even if it's 10+, I'm still under 1 min on most of my runs.
I never did have trouble with MoP running out, just cast it on a raptor in the boss group and there shouldn't really be any trouble.
