I have been doing some exploring with my TFO half weight and start fishing some really small water. I found a tiny trickle of water that just happens to be loaded with little cutthroat that violently attack dry flies. There were a few large 13 inch fish I spotted but they were in spots impossible to make a cast of any kind into. The fish were extremely spooky, I was crouching and sneaking around trying not to spook the fish. There was some cool spots about the size of a kitchen table and 3 inchs deep that you could see were devoid of fish but when my dry landed on the water fish darted out from under every piece of wood and small under cut to smash my fly. I'm glad I brought the half weight rather than my 3wt because there was very little room making it a struggle for even the 5ft half weight to cast.
