If you want to fly on the outside, then DO NOT be non-current when you leave the service. I spent the last three years on a non-flying staff job. I'm paying to get my instrument currency back in a Cessna, and haven't gotten even a nibble on the job hunt for a flying job. If you're current now, there's jobs to tide you over until the legacies start hiring - if that's what you want. But 3 years from now, having not flown in that whole time, you'll be unlikely to land anything at all flying.
