Hi all, I know its a bit comparison here. A little bit of bg info abt me, I play singles in intermediate level, I use the Astrox 77 4u version. Have been loving it but my coach recommends that I get a spare second racket cuz we are starting to train really hard. I have mostly an attacking play, but I need to cover up my weakness which is quickly changing pace from a slow game to a fast game with drives. Please suggest a racket from the above, I would like it not to be too head heavy and also has a good sweetspot. Thanks in advance.
