exactly. i've been riding long enough and on enough bikes from fully rigid to hardtail to 3, 4, 5, 6 ,7, 8" of travel and figured out long ago i'm at least as fast and have the most fun on a 4-5" bike than anything else for where i ride 90% of the time.Unicorns.
That's the point. It's hard to get a 6" travel bike that will have the acceleration out of corners and backsides that a 4" or 5" bike can. And if the design/setup exists, then that same design and setup would still do better in a 120-130mm application.
