May not be applicable b/c I use a spinning reel and it's harder to keep my presentation in front of my float. I put all my shot under the float to the leader...equally spaced to the swivel. I leave my floro leader absent of any shot so the current can take it easier. For the creek you and I know, I'll leave about 1 to 3 feet of mainline under the float to the leader, and then use a 2 to 3 foot leader depending on the flow. For high, fast and murky water, the leader is shorter but from the swivel to the float is longer...keeping the bait lower in the water.
I've re-read this and I dont know if it make sense to you...but it does to me....LOL.
