145g for a 27.2@350mm seems a bit on the light side, even for 7075 Al? I would expect closer to 185 or even 200. Maybe it's a typo. . . three times (one for each diam.). And if it really is close to the claimed weight is that really too light to be trusted?
Token has virtually zero presence, that I can tell, in North America so. . . could be moot.
