As a Catholic, I can see the merit in both sides. I actually struggled with this issue a while back. To me it came down to a few points.
First, I accept the teaching of the primacy of Rome. I see it in the Bible and it is logical to me.
Second, while I totally understand the development of doctrine issue that the EO have with Rome, and to an extent I agree, I do not see any logical reason why 1000 A.D., or any other point, should be the cut-off. Either we can understand and define doctrine as the need arises or we never could. To say that anything after a certain council is invalid does not make sense to me.
Third, so many of the Orthodox Churches have strong ethnic ties that I am not a part of. I would not feel at home in a Greek Orthodox or Russian Church as I am not culturally either one. I feel an exclusion in that set-up.
Finally, the Filioque issue to me is not that big of a deal.
