First - float & fly is great. Float & jig is equally great.
Second - check the regs - ODFW's streamlining has eliminated April openers and pushed it all to May OR opened it year round. I'm excited as a kid in a candy store because almost all my favorite small waters are going year round in 3 days. Yeee! The Mt. Hood streams may be closed, but lots of water in the valley is opening up to 12 months of fishing instead of 5.
Third - spinners work reeeally well in small streams. Panther marten, mepps, and rooster tails are my go to, in that order anymore. Rooster tail QC has gone to crap lately and I find I have to tweak my spinners out of the package to get the blade to turn right. Not a problem with the other two. Not sure what gives. Favorite color combos for me are gold blade/ black body, rainbow trout, silver blade / hot pink body, gold blade / brown body. Good stuff.
Small crank baits work well too - think tiny though.
Good luck man. If you have the chance to get weekdays off - I'm in the market for a fishing partner this year. I plan on hitting some small streams with fly and spinning gear this winter and spring. Would be happy to try to get you into some trout. My days off are tuesday and wednesday right now, with Wednesday being my usual day to fish.
