Very nice, I'm jealous. Paramounts are moving up my list of must haves
real fast. My opinion (not that you asked for it

) would be to go with the DA group and keep the Sora and 105 far, far away from it. I'm all about modernizing, but it doesn't seem right to put low to mid level components on a frame that nice, even if the newer mid level stuff is an upgrade from the older high level stuff. I'd either keep the older DA or get newer DA to put on it. I
might could be talked into going with Ultegra, but I doubt it.
