A friend hit the Kalama last Sunday and it was so crowded he turned the car around and fished the Cowlitz. Based on the available water, I'd recommend the crowded Deschutes over the crowded Kalama. A boat solves a good portion of the problem in either case.
As for the redsides, I too am a pilgrim with Duggan. Maybe we can squeeze a steelhead Deschutes trip in too...worst case being that we're in the doghouse together!
