 Your cast, the beauty of fishing a hopper or grasshopper pattern or a terrestrial pattern on a fly rod is that you really want to slap that fly on the surface. You want to make it look like it came out of a bush or whatever and just landed on the surface. And that really elicits some big bites from big trout. And, again, even on some of the most difficult trout waters there are. I really like hot days.
