Thanks fietsbob, I will give it a go and see if either of the derailleurs I have wraps enough chain or have the throw between the limits for 8 sp. with a 34 large cog. I definitely plan to upgrade to the XT stuff, but just thought this would be a good way to get it put together and rolling sooner. Plus I am pretty sure the deerhead derailleurs were good derailleurs on par with XT. If anyone can confirm this and they work well, then who knows. The light action derailleurs, while not all that respected, worked beautifully on the Six Fifteen that came with them. Since it would likely be a temporary set-up, not sure I want to get into buying extra stuff like a shiftmate to make it work.
