you reeived some good info. from other guys i would add that you want to wait until that fish is pulling line out from under a light pressure from your thumb esp. when fishing kings. back in the old days of catch'em and rock'em this was the only way we would fish steelhead on the lower skagit, snohomish, and stilly. i've been doing it for over 40 years and i guarantee it works and works well. it does seem to work better in the lower stretches of rivers mentioned where the fish tend to be traveling it also is dynamite on summer steelhead. good luck
