Unless I'm fishing really clear water I will stick with mono, In creeks I use Maxima ultra green 6lb maybe 8lb at most, sometimes I'll go down to 4lb depending on snags.
No matter what line you are using if your pulling it through rocks or having the current drag your bait along the creek bottoms its going to wear on your line, retie as needed.
For Fluorocarbon leaders I also use Seguar Invisx. Not a fan of their red label.
