For nightmare players - Favourite plague heart strategies

So I'm on Nightmare for all except the map which is lethal (you get a lot more PH's)

This is my level and I'm fine with that.

My current favourite is sneaking in and planting the C4. Then firecrackers outside to distract the horde before planting the 2nd. A good 5 or 7 gun just in case you need to finish it off, and take out the usual feral that pops up.

Also to mix it up I use scentblock and use up all the sundry items my team have collected.

If the PG is targetable from outside, a nice 7.62 assault but look out for bloaters.

What do you folks like doing?
