I took a look at the frame specs of both the 520 and the LHT. For me, at 6'2" with long arms and legs, the LHT has better frame geometry, specifically the top tube length. The 520 would be a bit short for me. That said, I don't buy bikes; I buy frames and build them up the way I want. I am not interested in buying a bike and then changing things out before I ever use it. This is not for everyone, but it works for me. I like to peruse ebay and other on-line sources for parts.
