I can understand why he said that... But to ONLY go forwards and backwards, it's best to have a traction wheel. (literally, he said forwards and backwards only...)

What Ether said, in essence, was that many mecanum wheels used 45* rollers, but that other angles could be used--less than 45* puts the advantage to front/back and greater than 45* puts the advantage side-side in terms of traction. I assume that this is a correct summary. If it is not, then the original post needs to be modified, as that is where I got this from.

From that, it is easily (and logically) concluded that, for the optimal front/back and side/side traction, 45* is a better angle than many others. If that is not the conclusion that was intended, then better words need to be chosen.
