Any of the bigger lochs like Tay, Awe, Clunie, Arkaig, Quiach, Oich, Ba...all good lochs to fish with the minnow. Took many hundreds of fish from these lochs during the 80's with my old man. The good thing about it now is that when the rainbow boom hit in the late 80's many people went from this type of fishing to stillwater fishing so these lochs all got a break from the hammering they got at the time. Bus loads used to take 500+ fish from some of these lochs at a time. I've heard that these lochs have good heads of fish in them again and many people are fishing them again though with the fly
