NF Stilly??

Hi guys, I don't post here a lot, but hope i can still pull some info out of you guys. I've been hearing a lot about the NF Stilly lately. Is this the Stillaguamish River? Anyways, i've been hearing that the fishing for sea run cutts is very good. Was just wondering what is a good selection of surface and subsurface flies. I don't know if any is willing to give out this kind of info, but what is a fairly decent access point for the river? I've never fished rivers for sea run cutts before, i usually fish small streams for small cutts. Thanks guys. :THUMBSUP
