Hi all,
I apologise in advance for basic nature of the post...
I've been a part-time fly angler for a few years now having learnt my trade as a course angler in the south of England as a kid, and since moved up to Edinburgh. I generally fish whilst holidaying around the highlands and thus don't get out as much as i'd like. In the past i've always stuck to a single fly, normally on a floating line, and this has been ok for what i'm after - i get as much from being in these amazing places as i do from catching. However, i've started to visit more local, sticked fisheries and so am trying to learn a bit more about the art.
So, my question is (and there'll no doubt be more

)When and where is it advisable to start using multiple flies? And how do you go about attaching more than one fly to the leader..??
Cheers!
