What sort of presentation Merge Peacocks are for, and while I'm asking Peacock stepped? They look quite similar.

I use them for on the drop at a medium range distance or for a more sensitive detection (less surface film around tip) for just touching bottom.

When stepped wagglers first appeared, they were used a lot by matchmen trotting a far side line. The theory was that, in a usual river flow, the upper levels moved faster than the lower levels, so a stepped waggler offered less resistance in the very upper level where the flow is fastest, and the float would present more naturally. In this style, they worked really well.

Excellent, thanks to both of you.
