I agree but the average consumer doesn't care about WB. Folks who care about WB are a tiny subset of an already small industry. Giving less information helps the average consumer make quick purchase decisions. It's good that you can easily whip out your phone to look up tactics or Zumiez for WB information in the product before you buy though.
Be careful about using Zumiez as a source. I think they have a basic template they use for 8.25s that says 8.25 x 31.75 x 14.25wb and if they don't know the measurement they just leave it as that,so if that's what's listed for the deck you're looking at then I would try to verify it somewhere else. I've seen several boards on there listed as that and I know those ones are wrong because I have them.
They also call damn near everything imported even when it has "made in the USA" stamped right on top like most SC decks.
Tactics is pretty good in my experience. It seems like they actually measure them themselves too.
