Nailed it!
That declaration hasnt aged too well, though so much in gravel has changed in the last 6 years that not much would age well. Considering the hyper-changes, that Tamland Guitar Ted helped design is still really neat.
There is a perhaps key wording that allows this to make sense- the design was to be vibration reducing, which is why 853 wasnt use. I am not aware that 631 reduces vibration better than 853. There has to be some abbreviation in the reasoning as listed on the review.
Different tubing models will be equally stiff if made in the same diameter and butting.
Perhaps the 853 was going to be too stiff due to some/all the tubes being larger diameter than the 631 that was selected? That could make sense.
