Don't loose the spoons but use them with FF. Often time I think the FF combo brings fish into the spread and as they peel off they hit the spoons if not interested in your flasher/flies.
Run a 11" flasher with a 4" fly with some glow on both for early AM bite first light. That will hit many days w/o question. Early Am you don't need super long leads so say 30 ft behind the ball to start and extend as the day gets bright.
I run 1 11" and 1 8" flasher for early am.
On my lead core i have spoons for later season mix. Coho prime time run 6" orange/red dodger with peanut flies for Coho with some spoons for hot action and run a 4" fly on DR or wire dipsy for a king.
I normally run mostly FF on my DR and Dipsy setup and mix in a spoon. Bonus king during Coho bite will light up the back of the boat in no time.
I run 18" on peanut flies
21 on 4" flies
Peanuts if you run shorter that is fine some go down to 12" and on 4" files some go to 24". Whatever you go with keep them all the same for each type and use your speed to alter the action is key. Also run 40-50 leader on the files to give them more action. I use Seaguar STS Salmon Fluorocarbon Leader Fishing Line, 50-Pound/100-Yard, Clear which is much easier on the wallet then some FL and loop up heavy leader knots on youtube. Three hoops and one thru from the backside and slips down to the hook for easy hook connection for peanut files. For 4" flies just snell the hook(s) I use #1 treble and 4/0 single hook to tournament hook. Guy named Bill has a youtube video that talks about the devil is in the detail and has a multi boat charter fleet.
