Is there a big difference between 55 and 60? My current stick is at 55 and it feels way to powerful IMO. I hit balls deep often when i take a normal full swing at, even watching my form. I would like for me to have to put a good effort into it to rip the ball, so I am more in control of the shot, rather than the racket doing it. Trying to figure out if 5lb is a big change. Dont want to over do it!
