I jumped ship this year and bought a '14 Summit XM 163".
I have no brand loyalty and made my purchase based on demos of all brands several months of research.
2700 mountain kilometres on it so far, and while it has not been problem free, I am quite impressed.
The 2013-14 etecs are proving to be very reliable and durable. They are a completely different experience than older 2-strokes, and even other current 2s'.
Build quality, I feel, is significantly better than poo and cat. The refinements and details pertaining to a mountain specific sled are hard to ignore. The whole package simply works, and very well.
Keep in mind my observations and experiences only apply to the mountain segment. I think if I was a trail rider, I would most likely be on a Yam 4s.
Not trying to cause a ruckus here, just that they are not the smokey 'ticking-time-bombs' of yesteryear.
