^I don't think he means that.
Are you asking if it will be faster?
It depends on the trail.
Lots of important races are still won on hardtails.
Most people who ride for fun gravitate to FS.
In my opinion, 2.7 lbs is a small penalty for a much better riding bike.
But if I had to buy a new bike for the riding around here, it'd be a hardtail.
