If there is marked improvement and WDFW decides to go selective gear rules I would hope that it is in effect over the entire state and not just one system or area.
If it's decided that delaying the opener two weeks helps fish then it should be applied statewide also. If it helps fish it helps fish.
What I don't like to see is special restrictive rules on one system and none on another. I don't want to see from June 1 through June 14 everybody hammer the upper river. Or everybody hammer the nearest other system. I also don't want to see X river has good returns so you can use methods proven to increase mortality while on Y river with poor returns you must use methods that decrease mortality. If changing methods helps the fish it should be applied everywhere.
