Straight TPEs in standard disc sizes tend to mold up light, under 150 grams for most. Manufacturers use heavier additives, like metal salts, to get discs closer to thier maximum allowable weight. You see this as the "pearly" or "swirly" streaks in Champion plastic.

I just weighed a Champ Teerex I bought directly from Innova - says 175 on the disc, comes in at 177.7 on my scale

Every measurement device has a margin of error. Have you ever calibrated your home scale/verified its accuracy? Being off by a couple of grams isn't that surprising for a domestic scale. And I doubt that Innova and the other manufacturers use analytical balances to weigh their products.

Moreover it has been said in the forums here that plastic weight can change over time based on humidity...

Did some quick Googling the verify: http://www.ptonline.com/columns/dime...molding-part-4

Innova weighs discs in groups, then averages the number, which is then written on every disc in the group. They usually get within 2 grams. A 177 gram TeeRex would be illegal, they are only approved to 175.1 grams max, and a heavier one would always be better in a headwind, so if I were you I would just clam up and throw that puppy.

I've got a Polecat marked "175" that Marshall Street weighed at 178. No problem as far as I'm concerned. And yeah, that Teerex would never be marked over 175...

I don't think a few grams of weight makes too much difference in the grand scheme of things. In other words, does 175g really make that much of a difference compared to 171g? Obviously we feel it might, so we favor certain weights. But I imagine most of it is some kind of juju that wouldn't stand up to any kind of real test. It makes me feel better when discs have higher numbers on them, so I'll just stick with that...

It's entirely possible my scale runs a bit heavy. Most of the time when it's different than what is marked, my scale says heavier than the disc
