Poly leaders as sink tips
This might be a variation on Double L's sinktips thread.
I was putzing for sea run cutts and maybe an odd steelhead yesterday with my Spey Tracker. I wanted to try a deep sunk fly but haven't made a Spey line with a sink tip for this rod. I looped a 10' fast sinking polyleader to the short head (52') line and it was like I didn't know how to cast this rod (perhaps almost, but not quite true). I was just flailing and couldn't seem to roll out any amount of line . . . until I accidentally slowed down the casting motion after pulling the line up to my anchor point, I slooowly formed the D loop and pitched the rod forward, and chucked the whole works out there as easily as with the floating line.
Now I'm puzzled as to why that appeared to work. The polyleader added 10' of length, but it was a trout sized and not that much weight, but more than without. Why would the slower casting motion pick it all up and send it on its way?
