I don't know much about the Fuji but I do have a buddy that bought the Salsa and sold it after one ride around the parking lot. His biggest complaint was the top tube had very little to no slant. He bought the bike that Salsa told him would fit properly based on top tube length. Once he received it and built it up he didn't have any standover height. That was a problem. After he sold it he decided to order a SC Blur XC. However after having constant problems with ordering from Santa Cruz he decided to go with an Ellsworth.
Now, from everything I have heard the blur xc is an incredible bike. It is much nicer than the original blur for xc riding and racing. A couple of my other friends ride them and they seem to be very impressed with them. The bike is pretty light and very efficient. They both use the blur xc for racing but they also do a good bit of all mountain type riding as well. If you can find someplace that has the blur xc in stock then go for it. Good luck if the shop has to order it though.
I may be fat but I'm slow enough to make up for it.
