Vater sticks are computer matched by pitch and weight AT the factory. For some reason, somebody between Vater and the UPS person who received the shipment (I'm looking at you, AMAZON) decided to un-pair the sticks from their Vater sleeves, then repackage them in a long, plastic sleeve with the Vater sleeve folded up next to the sticks in the baggie. I could tell when I opened the box that it wasn't going to be right, and as soon as I held them in my hands, I knew they were different weights. Visual inspection showed one stick obviously longer than the other, and if you look at the photo of the butt-end of the sticks along the ruler, you can see that the cuts are at different points of the curvature. There was a difference of 6 grams between the sticks. I've uploaded photos of the initial shipment.
