there is a rumour at the minute that not all the cadets are being kept on this year. About 20 of them may be laid off for winter and brought back in spring. I should imagine they will take preference over the hold pool until they are reconciled. Demand for commands will vastly exceed supply next year so any potential DEC's will need a liferaft in that pool. I can't see them offering much choice of fleets either. 737 is shorter on crews. When you're on it you'll be fleet frozen for 3 years unless it suits the company so the chances of being stuck on it are large. The european contracts seem to be in vogue at the minute..particularly MXP.
