I have just signed up here and and this questions has been raised 100's of times but I am new so I have to ask. I am down to the 520 and the Surly LHT as choices for my first touring bike. I have ridden both and still can't decide, I liked them both. I would be on a 57 Trek and a 54 Surly which would give me 26" tires. This is likely my biggest hangup now, whether or not 26's are as good as 700's. If you have any thoughts on this or any other aspect that may help me decide I would greatly appreciate it as I have been stuck in this debate for a few weeks now and I just want to get a bike at this point and get riding. Thanks.
