I think so. I just tested positive for GAS-23 today (ARS-90kii variant). Looks like we have an epidemic on our hands
My 4ug5 90kii strung with Aerobite at 27lbs with stock grip and stock plastic wrap on handle weighs 90 grams. Is that typical for a 4u racket in this condition or is it on the heavier end of 4u?
Judging the ever changing variants in new top tier rackets, you probably have to also switch budget rackets every 2 weeks to keep up the immunity. XD I would say yes you got a pretty heavy version. If we think about the goal of a 4u between 83g - 85g on average. Aerobite string potential added 5g - 7g in weight :O to reach 90g.
