Hi all.
I have been flyfishing for a few months now, and my casting has improved to the stage where I rarely hit my rod tip on the forward cast, (happened twice in 8hrs fishing on Sunday

) and only occasionally get a tangle or a knot forming unless its quite windy.
I have been fishing with a single fly on a 9-10 foot leader of monofilament.
So far I have only fished small stillwaters.
I want to increase my skill level(and my chances

) and try using 1 or 2 droppers, so a few questions if I may :
How long does my leader need to be?
Do I stick with mono or should I try fluorocarbon, or move to tapered leaders?
How many droppers should I tie on (2 or 3?)
How long should the length of the droppers be?
finally what flies combination should I try?
Sorry to ask so many questions in this post, but I want to progress a bit.
regards,
Gary
