The TCS crew and I like to fish small streams that sometimes could be describe as mere trickles. Casting is difficult at best, so we like to use our 6' 6" Eagle Claws and often go against the grain and fish downstream. It isn't easy, you have to move very slowly so that you are not kicking up a lot of debris and scaring the fish. This is tannin stained brook trout water so there is some leeway but it isn't much when it comes to lots of crap washing down into the fishes face. The casting is a little easier. I like the parachute cast and I like to extend the drift by shaking out the slack line. This has worked well for us in the past.
Here is a little video from the guys at Orvis that demonstrates the parachute and pile casts. Orvis often has tidbits like this that I love to re-post.
