Suspender buzzer 16.
When they are on light olive buzzers shucks they'll take a claret suspender. Sorry I can't explain it - and often it's the only way to catch them without "knocking them off". I've done really well with this fly on all the major stillwaters. In fact claret's just a great colour anyway - everywhere.
Tying instructions:
size 16, claret thread, claret seal, mono rib, poly ball in doubled stocking.
