I had a Head Ti s1 4 3/8 grip racquet. It was fine with me, I never felt I have to get a bigger grip. Two days back I ordered Dunlop Aerogel 200 (4 3/8), (18*20) unstrung racquet to strung it with Topspin cyber Energy string. Yesterday only I found this site and measured my grip size as shown in the site. Surprisingly I measured as 4 1/2 grip then I tried the Head racquet with two napkins wind to the grip:-D . I felt more comfort and realized 4 1/2 is the correct size. Now I have 3 choices : 1. using heat-shrink sleeve 2. using overgrips 3. using both of them. Please suggest me a choice or better method. I really want to keep my bevels and should be 99% like 4 1/2 racquet. If nothing works fine I am thinking to give without opening it. As I cant post a message in TW as this is a new one. So please suggest me some forum or something but nothing like **** or amazon who charges. I am thinking of giving it to $120. If any of your friends or some one looking for this one then they can reach me at sharath_vk*at*yahoo dot com or svallam at uark dot edu. Thank you.
