This is great--it sounds like I win no matter how I go! Good news on the tires. If I don't have to replace them right away, that makes the 5.2 more feasible. I'm still confused as to the double versus triple. I was surprised to see that 50X12 has a higher ratio (is that what it's called?) than 52X11. That bodes well for the compact double. I currently use my 52x13 a lot, and I was afraid of losing that range of options with the compact.
