But yes, I do much prefer the 650b, however, I do love that blue. Transition always put my first choice of colour on a wheel size that I wouldn't buy! Nevermind...
On the hardtail subject, I would never actually buy an Alloy hardcore hardtail. There is too much trail sting through the frame, they are just not nice to ride. Steel of one type or another eliminates a majority of that sting, yes they are more expensive, but worth every extra penny!
The 650b one is nicer....in this, isn't it.
