In time of preparing of my lake fly box for next year trips to the Czech Republic fisheries I have tied a olive buzzer. Covering a body of the buzzer is important because than a weight of a fly is higher and the pattern sink better.
During fishing worth to have a leader made by fluorocarbon quality line, this type of line sink faster than traditional monofilament lines.
