PACO, those are some mighty fine lookin flies. I'd imagine that they throw off quite the wake coming through the water. Probably good even when theres a decent chop on the water.
The heads about 3/4 a inch. The total fly is about 7 or 8 inches. With a floater there a subtle pop and wake. If ya put em on a intermediate it looks like a brick thrown in the water behind your fly. There's alotta stuff going on in those flys. Wire bending, crimp sleeves, rattles and the jig skirt.
Jig skirts raise muskies. The ghetto tramp which incorporates a skirt has raised all but one muskie I have hooked up on this year and had follows from. For whatever reason they like it. Like those poppers Paco, it looks like the Euro Pike guys are rubbing off on ya.
