Man, this thread died fast!
Ordered the 6.1 from the BF sale. Here's the stats with the plastic on the handle:
336g, 290SW, 29.8cm
335g, 290SW, 29.9cm
335g, 288SW, 29.5cm
335g, 297SW, 30.1cm
The place I got the SW measured, I also had them measure a few of my strung racquets and the measurements were spot on to using the app at home. So I don't think their machine was busted.
I'm really surprised at the low SW numbers, they would easily be under 330SW strung. The store guy and I shared a laugh when the weight measured out to all within 1 gram. Not sure how many I'll keep, but I'm happy that they were all under 305SW.
