One fly

[rannoch raider]

Now, that's a gathering I'd have bought a ticket for ! ;-)

I suppose for the sort of fishing I do (trout, running water and stillwater), if I had to restrict to one fly then it would be either a shaggy black klink/emerger type thing, or a small balloon caddis.

I would pick the following
Trout loch.....claret half hog
Silver.....cascade
River trout....cdc emerger
Sea trout.....big black and silver.

Lots of others needed for river trout in particular but hey Ho.

Trout still and running water GRHE

[Chase]

Running water only because I have no idea about the other stuff .Hans van Klinken - Lead head nymph , its a cased caddis thing . I use black tungsten beads instead of lead split shot.
By varying the weight ,it can be upstream dead drift or moved slightly .
Then fished down and across ect - used as a streamer .
Awful to cast and fish with but I would imagine catch fish any where .

[Inverguseran]

Loch for trout : Sedgehog
Loch for silver : Muddler
River for silver : Stoats Tail
River for trout : Deer Hair Emerger

[scoobyscott]

Loch trout bibio
Loch silver Pete Ross?
River silver? Orange and black shrimp type
River trout copper beaded ptn
Never fish fir silver so just taking a guess

a lot of cheating going on here.... one fly: not 4 or 5  :lol:  i would happily use a g & h sedge for carp & pike. albeit a bloody huge one for the latter  :
