Actually the truth is just the opposite in my experiance, Winter run fish have been much less agressive, in MHO due to the colder flows. You will notice after catching fish during the summer for a few months, they are extremely agressive and highly acrobatic, making long, fast runs, and fight extremely hard while being tired. Winter fish on the other hand tend to be more lathargic (due to the colder tempatures), pound for pound, the level of agressivness has statisticly been higher for me during July, August, and September. Although winter fish are on average larger fish, they do seem to loose steam when the frosts set in, but that's not to say all Winter Steelhead are logs.I might expect the winter fish to be more aggressive.
