I got my piano wire in the mail several days ago. I didn't know what size wire to use for the 3/0, 4/0, 5/0 hooks. So I ordered a size #2 piano wire to start with. After examining the wire, I felt that it was too small for the big hook sizes that I had originally planed for. So for a test drive, I tried on hooks size #2 (Mustad 3407DT). This size# 2 wire probably is good for hook size 2, 1, and 1/0.
The piano wire came in a package like this, 10' length, and costed $7 included S&H.
I cut the wire into 4" pieces and bended them double with fingers.
I measured the wire on the hook and marked the length with a marker.
I bended the wire at the marked point and secured it onto the hook. Placed a drop of Thin ZAP A Gap on the thread and wire to lock it into place.
The rest is pretty much standard tying process.
Here is another fly (a Half & Half) with a piano wire weed guard.
These flies are about 4" long.
The next step is to test them in a local FP lake choked with weeds.
