1. I'm casting a full Rio
Skagit line and didn't know how much of the dark "loading" indicator I should have out of my rod tip? I currently have been using about maybe 4" of the black color out.
extending your overhang can help prevent you from blowing your anchor...
2. After I'm peeling the line off the top of the water, and am making my forward cast, when do I put more "power" into the cast to make it go further? As of now, when I initiate more power, the backwards D loop goes too far back and snaps the fly and leader out of the water and hits things behind me. Which apparently shows i'm overpowering it, but am unable to figure when to put more "oomph" into a cast to get it out.
smooth acceleration to a stop.
3. Which part actually is anchoring the cast? The sinktip leader? Cause my skagit head has been pretty much out of the water by the time I'm making my forward stroke. (not using a cheater)
half out and go is the general principle, meaning when you see half your sink tip out of the water begin your forward stroke.
if pulling your anchor is still preventing you from applying as much power as you would like consider setting your anchor and then allowing a couple seconds for your sinktip to sink before going ahead and forming your d loop. this will allow you to put more power into the sweep and d loop formation. if done right your forward stoke should be the part that remains the same not the part where you apply the majority of the power.
this is all borrowed and interpreted info from various resources i dont claim to be the expert but i hope this helps...
