My personal preference is for Gargraves flextrack. It is very realistic in appearance and you can make any curve radius you need or want plus you can route it anywhere you want it to go. To me, Fastrack is not nearly as realistic and very unforgiving as far as routing it where you want. Last year I converted 565 feet of tubular track to all Gargraves. Very happy with the result. Have fun with whatever you decide to use.
