you do not need a leader for small mouth. use good line, a good knot and re tie often. Yes you will lose lures to pike.
Fish on their bed are not normally eating the are focused on breeding and protecting the bed. You need to trigger a strike from something they see as a intruder. they probably will not chase anything that is not directly in their bed.
I like a drop shot so you can put it right in the bed and keep it there. you can use a wacky rigged sanko on a drop shot if that is what you like.
The fish will often leave the bed then come back and hit the bait. even if your boat is within a few feet.
If your going to bed fish be very careful with the fish and return them asap.
