Hi all, I am looking for a head light racket with a medium flex shaft, I currently have a babolat xact infinity light however they seem to break too easily as they keep getting small cracks in them.... I have seen that Mantis are selling a fair few rackets with the specs that I like however I can't seem to find anything on them online, anyone had any experience with these rackets that they'd be willing to share? I would greatly appreciate the help.
