31m, 6’0”, 145lbs - 80 lb. weight loss when I was 21. Will Evolve work for me or do I need something more invasive? (Photo)

Hello. I am a 31m, 6’0” and 145lbs. I lost about 80lbs back when I was about 21, but I have struggled since then to finish flattening my stomach. Despite regular exercise and a fairly clean regulated diet, I have never been able to lose the last bit of belly flab. I have lost patience and just want it gone, but I am not entirely confident in figuring out what procedure I need. I like the sound of evolve for both less fat and more defined abs. But do i need to bite the bullet and go for something more invasive like SmartLipo?
