I've noticed that Yeti sizes appear to run a big larger than what I'm used to. I currently ride a 15.5" 96 stumpy and i love the way it fits. I'm pretty short though at 5'7". The small Yeti 575 is 17.5". This seems like a big leap. While I did ride it (albeit, in a parking lot) and i could definitely notice the size difference, I'm not sure how that difference will play out on an trail. What have your experiences been with Yeti sizes? Also, 95stumpy - what size was your stumpy compared to the 575 you have now?
