Depends what you really want but in your position, I would at least try for a big legacy airline to experience different or more varied flying.
You might not get in, but you have nothing to lose by trying, and trust me, flying short-haul in Europe will start to get tedious after 15 years - let alone 29 years - especially with the ever increasing rules and procedures; tighter profit margins and fuel policies being taken out of Commander's hands.
Flying is not as much fun any more, but with a big legacy airline, you can at least move into different areas, e.g, try long-haul. (Not brilliant either any more, but at least you get to see some of the World).
If you don't get in, then you can fall back on trying to get a Command where you are.
If you do try for BA, then practice practice - and then practice some more ! They give you 30 maths Q's in 12 mins, and a similar extremely time-limited verbal reasoning test.
Good luck
