I 100% agree with the gambler. You'd be crazy not to do as much research on where each jet is going as far as assignments, deployments, etc. I would also add that you should rank your choices based on the mission you want to do. Don't simply list the raptor first because of what other people say. Only list it first if you want to do the A/A thing all the time. From your tentative list, it looks like you want an air to mud or multirole type jet. If thats true, put the -22 and -15C last.
