Hi guys! I would like to ask what's the flex and balance point of yonex mp25 power? some say it's flexible and some say medium... what is it really? and the original price? i have seen one which costs 100 plus dollars but in most websites it's 60 dollars only.. why is that? and, about the grip, is it common for the rubber to peel off when you remove the plastic from the grip? because the plastic is so tightly attached to the grip... how can you possibly remove it w/out peeling the rubber?
