my OP was more looking for an answer on whether or not the weight thing is true. it doesn't seem to be when the D dot is placed near the O dot, but it is a big issue when they aren't. something seems wrong, and it might not be the weight. could be the placement, but catch won't let us talk about that on the forums anymore and claims it is working as intended.
