Narrative:

Tower was working a traffic reporter helicopter which was close to final approach. We were aware of each other and visual with each other. Helicopter was maneuvering to stay clear of our flight path. Approaching 500 ft AGL. TCASII gave 'climb' RA. Since we had traffic in sight and he was no problem, I elected to continue to land. Also, considering that a go around at ord is very undesirable from a safety standpoint, with traffic landing on 2 other runways, and departing from at least 2 runways, I should have had the TCASII set to 'TA' only.
