I think a lot of it has to do with the way you fish as well. From a boat, I think it is much easier to use braid on spinners. For one a strong swivel, and palomar knot gets you back your spinner most of the time when you can get the boat over to it. From the bank, I like a 15' bumper for swinging or straight mono.

95% of my coho fishing is for fresh fish in 2' to 8' of water, from a boat. Getting deep is rarely as important as just getting it near a fish.

If I was working over holes with multiple angles and casts, like I would in a drift boat or from the bank, I would use mono or a long bumper.
