For Steelhead #12 Ultragreen as mainline. This year I tried something a little different. I used #30 Power Pro on a Ambassaduer 5600c4. This 6.3:1 baitcaster on a Loomis 1025c prooved to be the best setup for spinner fishing for big silvers in the river I have used. The fish were not the least bit shy of the line (#6 dia.) Positive hooksets and they don't come off. In addition you can feel everything. No more guessing...is it a fish...or a stick?
