True. I think the only difference between them though is a bit of weight and external cable routing vs. internal. I can tell you that when I was looking at buying my frame the difference in price between the 5 vs. The 6 series was definitely not worth it. With the warranties on pretty much any bike that you're looking at I don't think this should play too much into your decision. Keep trying bikes until you find your perfect balance of fit and feel. You'll ride more if you do. Good luck!
