Dont think .Take the job.Jobs r v difficult to get these days and then u will be flying a widebody jet.Have faith,it may b frustrating till u actually get ATLEAST 500 hrs on the Jet because if u dont,it wont b worth it ..........BUT DO U HAV ANY OTHER OPTION RIGHT NOW?
as far as jobs after u have 500 hrs on type r concerned,u will atleast b ahead of the other pack who havent seen or felt the Jet.
Take it,good luck
