Fiber-Wrapped- Lighter, and Look Much cooler. Max Life Of Tank, 15 years.
Alloy Tank-Heavier than Fiber-Wrapped. Doesn't look as nice, but, looks arent really everything. Max. Life of Tank, Unlimited.
My opinion. If you're going to go into the touney scene, and be serious about it, get a fiber wrapped tank. The weight matters. If the tank is for woodsball and the like, just get the Alloy tank, just because it will take the dings, and dents that a fiber-wrapped tank cannot. Since you will be running a remote, looks aren't the top priority. I'd go for function over fashion. E-mail with any other questions.
