Another issue with them (that I've read) is that they freak out when they see a sudden drastic increase of revolving debt reporting on the CBRs...especially when it is out of the normal behaviour of the cardmember.  Most people don't seem to see any AA from them after opening new accounts after their Barclays approval, but for someone with a young credit history and escalating debt, any issuer might react with a CLD or a closure.
