How are the optics on your U2K? I have one, and when properly collimated it is the best 8" SCT I have seen. It even outperforms a fellow club members C-9.25. I noticed that Ed Ting found it to be one of the better scopes he tested.
How about your other scope? I would keep the one with the best optics, but I would make sure both were really well collimated when I did the comparison.
