Don't be mislead by the 27.5 label. A 27.5 is not halfway between a 26" and a 29". It's actually much closer to a 26". even though I am tall enough for a 29 and ride some 29 bikes, I love the 27.5 wheel size. Accelerates and handles very much like a 26", but gets you a bit more speed via it's slightly larger size.
Can't help you on the Scott, but, as always, I recommend a test ride before you buy, even if it means having to travel a bit. Best of luck.
