Thanks for the replies, have to say I dont like flouro, I dont like its wiry characteristics, and it certainly isnt invisible in water but now I can see that mono being much softer will tangle more.
Rob, I did tie the dropper downwards but seems it was too long at 6 ins, the daft thing is after going to a single fly I had a brilliant day catching ten fish, best three going 7lb 9lb and a whopper of 15.2 lb which I know will take some beating. When I try a dropper again i`ll go for a shorter one and try Rons knot suggestion, oh and yeah my casting needs work
