So long as your weight isn't tapping along the bottom, i.e., driftfishing, I can accept a little bit of weight on the leader...but there's no way whatsoever that a strike indicator and weighted fly is anything but float and jig fishing with the wrong rod...and dragging a bead on the bottom with a strike indicator is bobber fishing, whether you do it with a spey rod, center pin, spinning rod, or casting rod...

Fish on...
