Hi Bombastic,
for what it's worth I've worked for Ryanair and sat alongside many colleagues to my right. I've seen many very good candidates who came in via a cadetship with no airline experience but would always feel slightly more comfortable with one who had "served some time" on TP's. I've also had conversations with Dispatchers looking for their first job on the flight deck and have always given them one piece of advice - "If you can then fly a turboprop first". My main reason for that was that WHEN an airline the size of FR goes pop there will be around 3000 FO's with the same rating as you UNLESS you have experience on another type in which case you will have a slight edge. I'm not sure how this helps you but you can replace the term TP for any other type as in small jet. Just my own opinion of course.
