I was ATC for 11 years, 9 years USAF and 2 years at Houston Center, and 90% of the time I'm glad I made the switch. There are those times when I won't be able make my commute home or bad weather days that I regret it, but overall I love flying more. And I'm still at a regional, can't imagine how it'll be once I make it out.

Good luck with your decision!
