I have 2 of those (one "strat" and one "tele") and what you describe are there, open G (especially that one) and high E have that "not ringing as it should" problem.
I did hear the problem directly but the strat (first I got) was just so good that I didn't care.
They feel like and led friend directly from the box, a year of playing and they will be keepers for life.
The problem are so easily fixed, I mean. I will put the "rod" thing you have on the edge tremolos there but have solved it by just wrapping a bit of extra string on the string pole, and that is enough.
It would acctually not have the problem if it didn't have locking tuners, so you would add more turns. Adding the turns sort of makes the locking part pointless.
With that said, the guitar stays in tune well and playes fantastic, they really are fantastic guitars. I am not a fan of the pickups, they compress (like most Duncan's) to much for my taste. But that to are easily changed when it is a rainy day.
Here are my talmans. I also have a bunch of the old ones but these new ones blow them out of the water.
