Clyde touring bike dilemma
this year I am doing a couple of multi day rides 350 miles/ 4 days - and 600 miles / 6 days. For now I am equipping my Giant Defy 1 with a back rack and bags. I plan on camping each night with a small tent, and travel rather minimally. This will likely be a later this year purchase, but I tend to over research. At 6'4" 250lbs I have a hard time finding any to ride, I have found a 720 and a Sutra that I stood over which were too small. I have rode none of these.
If you have experience with any of these I want to hear from you,
The question:
If all three of these bikes are the same money which one do you prefer and why?
Trek 720
Surly Long Haul Trucker
Kona Sutra
Thanks in advance.
