The basic Grand Bois are vulcanized and didn't do so well in the tests. However, the newer "Extra leger" versions weren't tested. He notes these "feel" supple but testing would need to determine what actual rolling resistance is.
We can pick on details of testing, but it's enormously refreshing when a magazine grapples with real numbers rather than doing a few test rides and reports on how the tires "feel".
