Dual nymphs

......no, not hot big-boobed babes drooling over your rig!

I'm having no luck tossing out my lone oversized dry BWO (#12). OTOH, I've
improved my casting immensely. In light of that fact, I actually broke down
and spent big bucks on 3 flies from my local premier FF shop. The guy on
duty seemed to know his flies, but didn't know the basic nX equation for
tippets, so I'm not sure of any advice he offered other than to rig 'em as a
pair. So, the question is, what's the best way to rig a dual nymph
offering. I have a BH pheasant and a Dunn's emerger. I also got a hotwire
prince, but I figure that's a solo rig. What say ye? TIA
