Duckster,
Never even considered putting these on the fly line...They are difficult to cast with the long tippets....
Thinking out loud here...
Problem is that a 'floating' line won't sink beyond the peg/float, so that's not going to help much...sink tip would work, but only if you peg at the 'transition' from the floating to sinking line, which limits your 'depth' choices to the length of the sinking section plus leader/tippet...may be workable by adjusting tippet length....as long as it's not 'too deep' that would still cast easier.
Having the float/peg on the fly line itself would certainly make casting MUCH easier....have to redesign the peg...needs to have a larger opening, but that's not too much of a problem....With a 10' sink tip and a 12 foot leader, that gets you to 22'... should work, I'd think...even if the peg doesn't slide past the fly line to leader junction, you could still land the fish okay with a 12' leader on a 9' rod. Before I figured out the whole sliding thing I used to fish with 15' tippets and land fish okay....seldom fish deeper than 25' anyway...
This could work. Would certainly make the 'normal' depths used with this technique, from say 15 to 20 feet, easier to cast.
Thanks Duckster!
Now it's back to the design stage again...maybe the barrell of a cheap ball point pen for the peg...
