Position Choice.
I personally have read all the links etc and knowing the industry well and your particular circumstances I would offer the advice as possible.
Corporate
Its a great position your being offered with your Low TT in addition flying a nice corporate Jet, down side to this working in corporate these positions can leave as soon as they arrive in addition you will at best do maybe 400 hours a year.
Ryan Air
we all know how good bad and indifferent the Airline can be etc, working under EU OPS lots of sectors, weather, passenger loading MMEL items, crew duty times, crappy hotels, Fuel police on your case. 900 hours max per year.
This is the best OJT you can get at your level and take the 700 rating do you time and in 3 years time you should have 3500 hours under your belt.
You need to be in a structured operation gain all of the above and then consider the choices.
Your a very lucky person to have options I know so many TYPE RATED Pilots looking for work.
Good Luck in your choices.
