Biermuncher's OktoberFAST PM

I posted this in the recipe database thread but figured I'd ask here since there is more activity (hoping to brew this weekend).

Looking at 3 PM recipes in the thread... There appears to be quite a variation in the grains and DME.

Especially in the third one... 1lb less grains and 1.5 - 2 lbs less DME compared to the other 2. Is there a preferred PM recipe for this?

Recipe 1
4 lbs. Light DME
2 lbs. Munich (20 SRM)
2 lbs. Vienna (3.5 SRM)

Recipe 2
3.5 Lbs Light LME
2.25 lbs Vienna
1.75 lbs Munich

Recipe 3
2lbs Extra Light DME
1.5lbs Munich 20L
1.5lbs Vienna

Thinking of going with the first, leaning toward the bigger beer. Any thoughts?
