ISO Recommendations related to taking biologics for RA treatment

Dear neighbors, My treatment for rheumatoid arthritis has reached a point where I need to make a decision about whether  to take the next step up to a biologic (namely, abatacept or etanercept). I’m wondering whether any of you have had any experience with either of these (or with biologics in general) that you would be willing to share with me, either by email or by phone. I’m also considering going for a second opinion and would appreciate any recommendations for the rheumatologist you found most helpful in making your decision. Thanks, Claudette412-441-5802
