ATR Captain or 737-400 F/O???

[aircowboy]

Hi guys,

I'd like to know what would you do in my case. I have been offered an ATR 42 Captain position and at the same time been offered a summer contract to fly the 737-400 including off course the 737 type rating (CL and NG). What would you do? I have assumed I will make between 300 and 500 hrs, but I wonder if the hours on the 737-400 ares still "valid" to look for a job once the contract is over.

Thanks
