I think you should fly a turbo prop if you feel that flying a turbo prop is something you really want to do and you should fly a jet, if flying a jet is something you really want to do. Don't see a turbo prop as a limit or a jet as a limit, when the sky is your limit and the world your oyster.
Most take the first thing that comes along through and that is fine too.
Let life be the dancer - you should be the dance.
