i just got a 2U G5 Arcsaber 11 from Hong Kong
Do 2U racquets have a big difference from 3U racquets besides the weight?
Are they more powerful or slower?
And also does anyone know if professional players ever have used 2U Arcsaber racquets?
Generally 2U would be heavier than 3U, however if you compare higher tier 3U and lower tier 2U, the difference would not be so significant. As 2U is heavier, it will be more powerful and slower, provided the users can wield it, otherwise, it would be less powerful and slower.
