Exactly as I found. Keep it coming.
One batch of mozzies gave me problems. Blind tested them and also with another shooter. One batch gave vertical stringing (no wind at all), other didn't. Also tested an old batch of AA fields, which were as good as the good mozzies.
I wonder if it's related to head sizes. Certainly though i've found more variation between batches of the same make than between good batches of different JSB clones.
This is probably why you might read some shooters saying that suddenly their gun likes a different head size.
