I am looking for a CC that earns most UA miles. This will be the first UA card for me.

I was reading this threads and appears that "United Mileage PlusŪ Platinum Business Card" gives me the best milage promotion.

Is there another UA milage related CC promotion which I could take advantage?

For what I see, applying two chase CC and consolidating the bonus miles from that two CC is no longer working, correct? (stopped as of NOV, 2006)

So, 25K is the best option for me? Any suggestion is greatly appreciated.
Thanks in advance.
