Teeny sink tip lines are great when used for the right application. While I have nymphed with a sink tip and swung it at the end, I don't believe it is nearly as effective as a long leader dead drift technique, especially for a beginner. When you can dead drift without an indicator and set the hook by feel, then try a sink tip.
I am a huge fan of the Royal Wulff Triangle Taper indicator line. It's all i use and I have them in 5, 6, 7 and 8. I'm not on staff either. I paid full retail (it's worth it to outfish your buddies!)
