I would definitely try and get an LCA position at your current employer. It can only help (unless you allow one of the 250 hour guys to get the best of you ;-)

If you elect to go to the sim IP jobs, make sure you continue to fly enough to stay around the 200+ hour per year mark. I have a buddy who has all the blocks filled, but since he is an APD his current hours in the past 12 months is low. This is an issue for him getting in the door here at FDX according to the ACP.
