JMCUBIC,
I got my latest 6x42 (matte finish, Heavy Duplex) directly from Leupold maybe 6 months ago, and it felt heavy to me compared to the many older 6x42's I've owned, going back to single-coated M8's. I weighed it and it was right there with the 13.6 ounces listed. Maybe they've lightened them up again since then.
I've never weighed a 6x42 that went as light as 11.5 ounces, but it would sure be nifty if the latest models are that light!
I've weighed a bunch of 6x36's, again beginning with single-coated M8's and most recently with FX-II's. All went right around 10 ounces,
