thanks for the replies, and bikemig, I had already looked through that thread but I hadnt seen where anyone mentioned specifically that they had used the stock RD from the original 5 speed rear setup. As I said before, I'd most likely be upgrading the RD at some point down the road, but I hate seeing so many good parts sitting in my garage. I guess the only way to find out what works and doesnt work for me is to just try it. I can always put it back.
