Congrats on the weight loss program. Under 200# wouldn't restrict any sport plane I'm thinking. IMHO the MOST important part of the decision (assuming finance isn't an issue) is whether or not there are any SP instructors and schools anywhere near you. Next is how far away is an LSA available to rent. Here in the Chicago area there aren't many at all. Buying your own LSA is of course always an option if you have an abundance of cash available.
MOSAIC could still take a looooong time to be enacted, and I do agree that having the fleet of 150s and 172s available would eliminate the unavailable rental LSA reality.
