I said this a few days ago, and it might be worth repeating...
Is a slightly lower pay scale worth turning down the job if you are afforded the opportunity?...each candidate has to answer that question for himself or herself.
But then, it has always been an issue with those carriers that have fleets that consist of different aircraft types...so, why should it be an issue at Atlas?
When you are senior enough, you can hold the next airplane. Isn't that how it works?!!
Good luck.
