Since I started looking at AM bikes I have heard about he greatness of Intense bikes. I was looking at the 6.6, but the price tag is a bit of a shock for someone who is new to the sport. I can afford one if I wait a couple of months, but am wondering if it would be worth it. Is there really that big of a difference from a Yeti 575 to a Intense 6.6 or 5.5? Can you really notice the difference in ride quality? I was told by a shop that you will feel less fatigued when riding a Intense bike, is this true?
