Have to disagree with alot of what you are saying!!!
I almost never see anyone bottom bouncing unless they are trying to line the fish.
Controlling the drag with your hand is way better than relying on the spinning reels drag...I constantly see guys loose fish because they cant lock down the way you can with a pin nor control the drag.
Its interesting that 95% of the fish caught are by guys with a Centre pin,..not too mention 90% of Steelheaders use one. there are all facts. Most of what you said is heresay,..and I would bet yu use a pin >90% of the time.
