...oh well, after much thoughts...I am still undecided on which grip to choose, a 3 size (4 3/8 ) or a 4 size (4 1/2). If I use Wilson't printed measurement, I definitely and perfectly have a 4 size. And though I currently use a 3 size+overgrip in my racquet and feel it's a little too small (slightly), still I am scared to buy a 4 'cause if it's too big I can't go back. I am also scared of putting on plastic sleeves or extra grips 'cause in the first case I don't think I would be too good at putting it (plus I would pay more which I don't see why), and extra grips tend to round too much. This is all because in my city no tennis shop has a number 4 racquets...they all have 3 and say: u can always make it bigger...yeah, I know that, but that stinks. I want to order from TW and I am confused about it this thing! Please help !!!
