I'm more than happy with a finder guider on my RC8 @~1600mm, using pHD and DSI II pro.
When setting PHD, Just try to picture that you need to make big jumps to move a star in the finder guider scope, but you need little finderguider jumps to move the star in the Big scope. Adjust PHD accordingly.
After three years of trying all the guider combinations, to me the lightweight finder guider piggybacked seems to be the most reliable (and simple). See attached pic. I DO use good rings though, so it functions well as a finder too, I don't use a separate finder scope, just a red dot for general use, rarely these days. YMMV but good luck.
