Having BTDT I think you will find times have changed a lot since you left. The CFI reinstatement is totally unnecessary if you have previous 121 experience. Currency is pretty much a non issue these days this is definitely not 2003. You are one of those elusive "woodwork" pilots we often refer to in discussions about the pilot shortage. It's people like you they are going to have to convince to get back in the game in the future. Best of luck.
