Thanks for all the information. I have used full sinking lines in lakes before and found them very useful. I was fishing muddlers unweighted on a straight mono leader so the fly actually rode above the bottom when the line was fully sunk. worked very well and kept me out of snags.. first time with a sinktip. Price was right and well ah you know how that goes.. I will take it out as is and experiment till I can get it to work for me. I'm assuming a fluorocarbon straight leader might work best?
