Paul returns to the Isle of Mull and meets up with Duncan and Brian Swinbanks who have recently started a lure manufacturing business to keep them busy during Winter. He then heads out with Brian on to Loch Frisa, trolling some of these new lures for large Brown Trout, which are a feature of this water. Its April and with fishing lying deep, this is a great way to find them and Paul does just that landing a sizable Brown Trout. Fly fishing for Trout and Salmon gets underway properly during Summer but it's the sheer variety of sea angling that makes Mull such a great destination. Duncan and Brian invite Paul out for day's boat fishing with the challenge of seeing just how many different species they can catch in a day.
