Carp, Caddis & Rio Line

I have been trying and trying to find a good spot in the local river to try and catch carp on the fly but just can not find a spot where they are in sight, you can not blind fish for them. You stalk carp the same as you do bonefish. The only spot that I have found them and have caught them is near the Chinese resturant in Lewisburg just off Route 15 N., we call it Bull Run but I know this is not correct. I use a bead head crayfish like pattern and cast it lightly ahead of them and just give it some action and 3 out of 10 time they will take but in this small area it is dam hard to land one, give it a try next summer.
  I have been fishing Spring and Penns Creeks with success using any tan caddis pattern, Iris (emerger) or a Bubble Back adult pattern with great success. My killer black bead caddis wet emerger has had limited success but it is very early in the pattern testing to throw it away. Saturday Sept 15 I was at the junction pool of Penns & Elk/Pine a bit early, got dressed and decided to walk down the bank and come in from below, as I was dressing I could hear an Eagle in the area but could not see it. As soon as I came out from the stream side vegetation I waded to a rock to rig up well just below me in a stream side tree was the Eagle just looking at me, well got the camera out and turned it on- Message Battery Exhausted *** dam he flew off and I was just thrilled to be that close to him. Had a hell of a time trying to get a fly to the fish, every time I cast the leader would just fall on top of itself, cut it back and rebuilt it with limited success. I had to cast maybe 6 times to each rising fish to get the dam fly where it should be, the line was a Rio Gold WF3F and it will be burned this week, I tried a t least 3 different leaders and they all sucked. I did use the line before and had limited time with it but it's gone now. Any suggestions on leaders will help but please no Geo. Harvey formulas, they just are not accurate for me. I'm using Rio Trout leaders and have become more familiar with them and have had some good days with them but this was not one of them, the rod was a Winstion 8'6" BIIX- god figure.
  Anyone looking to buy or sell quality equipment might want to use either of these guys, they are far and offer a lot of rods and reels;
www.tradenstuff.com or www.ricksrods.com Dave at Traden Stuff has a huge inventory and it fast, Rick's is more for the high end stuff but worth a look.
