No!.... No, you won't miss going walking pace in granny gear up a steep techy trail, or declining an invite to ride from a friend because you "just went yesterday and my knees are blown", nor will you wish you could just "slow-down a little" to turn your magical uphill flow into a standard choppy disjointed climb, nor will you miss failing again to make it up THAT SAME SECTION that you never seem to master because you - just - don't - quite - have - enough.... dammit!
Hell, with the Rise, you won't even notice much when you have to pick that thang up and throw it around as luggage (perhaps the worst aspect of emtb ownership). My Decoy with coils both ends requires some machinations and brake-hold wheelies and rolling, etc. to get it where I need to go before I dare lift with a well-placed (CG) hand.
My wife did the reverse, she owns a Rise M10 but while traveling, we all rented Rails out in Zion UT. She had a good time during the 2nd half of that day on the Rail (mostly downhill, gorgeous views, and Utah!) but by far prefers her Rise. She says it makes her feel like she's on her old "Stumpy hardtail" (circa '96 mind you), and much more natural than her former Giant Anthem X1 29er which never seemed to win her over.
