If you care at all about driving experience and unsprung weight and the effect it has on handling, avoid RFTs at all cost. They are a great thing to have if you don't care about ride or handling, such as driving a SUV out in the middle of nowhere, but on sports cars, they are a BIG no for me. If you live in a city, you're probably a few minutes from a good mechanic or a dealership and I rather have the car towed when I get a flat than endure the crappy feeling and numbness of a RFT everywhere else.
