mstateglfr no offense.

The problem is that the relationship between pressure and rolling resistance isn't explicit. I understand the basic argument (what matters is the contact area. At similar pressure they'll be the same, but less deflection for the wider tire means less rolling resistance). I'd be curious to read about the patch size as pressure drops, the impact on rr and comfort. Let's just say that their blog entry pushed me to keep 2" (marathon greenguard. My previous tires were Supreme and Almotion, no longer available in 26" in any width). I've considered the Plus and Plus tour, but the weight penalty, worse rr and higher price settled the case.

2" is useful in loose gravel/sand. I don't expect a major difference in acceleration. And they are in the mail
