Its Loirston not Loriston. Has been fishing well recently and no signs of the weed that has plagued anglers for past couple of years. Fished it on Thursday with not a trace of weed on my sink tip line. Virtually anything will catch fish from buzzers,nymphs to lures. You have to find the right spot but fish do move round the loch constantly - you can go for ages with nothing and then see fish moving into the area you are fishing. You have about 10 - 15 minutes before they can disappear until they come back round again in maybe 15 - 20 minutes later. There are some hot spots but that would be giving the secret away and you really have to fish it to learn the hot spots.
