I could see 2 fish in the pool. I walked slowly up river while I considered my approach. As always, I didn’t wait and think for too long. It’s important to take the shot as soon as it presents itself but without being rash. I sent in a shot, landing the single weighted nymph ahead of and to the right of the fish. I had no indicator. The fish swung to the right and I struck firmly when he was in the right place. I had no visual other than the fishes mannerisms. I was too far away to see his mouth. When a fish cruises to take your fly, his manner will change after he has eaten it. He will turn, slow down, or change direction in some way. If you wait to see which one of these he does, it will probably be too late! Timing this strike is something I have learned from exceptionally close quarter fishing to lake edge cruisers when both fish and fly (usually a spider or nymph) are visible. To elaborate on one example, When a fish slows down after he has taken your fly his tail will stop moving from side to side. Sounds obvious, but the fish’s speed wont change for a moment or two after the tail stops and by this time it will be too late to strike. Strike when his tail stops! In the end, its down to knowing your fish and where the fly is. Don’t hesitate…. or do!
