I'm not an expert, but thought that this might help. Remember that weapons, or mayfly rigs, simulate a mayfly that has hatched on the bottom and is beginning to head to the surface. When making them, think dainty, you are trying to mimic a mayfly fluttering to the surface.

Mayflies usually appear in Mid May. The last couple of years the weather has pushed them back into mid June (at least the peak) if I remember correctly. You will know when they arrive in full blast once you arrive at the Lake.

I hope this helps,
