If you have a more balanced bike with a longer chainstay, then surely by default the rider is placed more in the centre of the bike, therefore the ass to rear tyre should not occur that often even with a 29 er. I'm 5'10 and rarely if at all catch the rear tyre, the chain stay lengths on my bikes range from 435, 443 and 455 (front centres within 2 mm of each other @ 775) All have around 460 reach. UK riding is very often at lowish speeds on hand cut narrow tracks, steep and twisty. The best balanced is the 443 RC bike 29er 130/120 which I sized down as a wanted agility v stability.
