SETUP #3
Find a lookout point. Get up high and get a good view of what's going on. Watch the edges for movement. Remember, just because there may not be an immediate spotting, it doesn't mean that one won't come. Be patient, be still, and watch. If an opportunity presents, set up for a cast in a location where the trout will be traveling to next. I find that placing the hopper between the fish and the river's edge is most effective, opposed to placement towards the centre of the river. Fish probably eat the majority of hoppers closer to the bank, so try to keep it realistic. I've been in many situations where a cruising fish just won't commit to a hopper down the middle, and one cast to the inside, close to the bank, is all it has taken to seal the deal.
Double- Up!
If you want to fish that foam high and dry, but want to double up on the amount of water column covered, try the always popular “hopper-dropper” combo. Hang a nymph below your hopper and cover all your bases. It can be very effective.
