Hope you decided on the ds. Had mine 8 years ago, same high weight and starting weight. I let the Dr. Pick the surgery and this was his recommended one based on my weight history, eating habits, etc. Thank GOD he did. I lost 175 lbs. with NO issues ever. Even now. I have known, seen and heard of so many people who have failed after the other surgeries. You must keep up with vitamins and supplements and follow up with the office as required. I see mine each year to do bloodwork and talk to the dietician/nutritionist. I continue to basically follow the eating rules. If I don't then my body rebels, and because of the ds I can't gain the weight back. I am a female, 5'8" and 57 years old. Good Luck!!!
