I'm not sure where to post this...

Was wondering if the new offer for 50,000 bonus miles on the miles & more credit card (found here https://www.barclaycardus.com/apply/...&cellNumber=11) was 1. worth a pull if I don't have any other Miles & More points right now saved up (maybe I could do better on other cards)? and 2. would another Barclay card like the US Airways or Arrival be better if I were to go for a Barclaycard?

Thanks.
