Concerns about the ex-strategy consultant

Monkeys,

I'm a consultant at a strategy shop that sits under a large T2 services firm (Think Parthenon/EY, Kurt Salmon/Accenture Strategy, PWC S&). I plan to go back for my MBA in 1-2 years, and am eyeing a potential move to an Associate role in IBD after that (I've found that I enjoy finance and am not half bad at it).

I know that this transition is fairly common for MBAs, but that bankers are often skeptical of consultants interested in joining their firm. So, my question is, what specific concerns have you heard bankers bring up about candidates that are ex-strategy consultants? I'd imagine it might be a lack of sufficient modeling experience, concerns about willingness to work banking hours, or other stuff... Regardless am curious to get some input from those on WSO who are in IB currently or have had exposure to this. Also, for any shortcomings, is there anything in particular you'd want to see a candidate demonstrate that might mitigate your concerns?

Thanks
