"That can be largely solved by having the weight (tool fly) below (at

of the tippet) and the target fly on the tag of the blood knot leader-
tippet connection."

Yeah, maybe. I use that rig when it's windy. I remember a trip from
Gray Reef damn down. That trip was the first time I ever fished
the Crazy Charlie for weight. My partner Wayne used split shot
on the leader and I used the Crazy Charlie. We both used itty
bitty blue bead heads on the end. Wayne's a better fisherman than
I am, but I was able to keep pace because of all the extra fish
I caught on the Crazy Charlie.

When it got windy I put the Crazy Charlie out on the end and I was
still able to fish, but the strike rate went downhill instantly. You
always
get the most strikes on the end fly, so you want to put the fly that
gets
the most strikes out at the end, if at all possible.

That rig (the Crazy Charlie used at mid-leader for weight) followed
by an itty bitty beadhead, is what I call the Gray Reefer, because of
that trip. Works great. But they're a bit hard to keep lit when it's
that windy.
