How "good" do you have to be before you go from getting retail racquets customized to having your own molds? What's the minimum order? Do they come from Austria? Which companies do the work? Head or P1, **** (I just did a Google search of racquet customization..all I really know is Wilson does there's in the Wilson Pro Room in Chicago right?) Is there one specific person for Head that handles for all pros? sn: How do you get that job!?! Can you choose from any racquet? Say you're playing and you say..."I really like the feel of the Prestige Classic" Can they make any racquet with any material, whether it be the feel of a "Classic" or an "iPrestige" series..is the sky the limit? You can just say...I want it to be "x" long in inches, have a stiffness of "x", a string pattern of "x" a swingweight of "x." Is there a form you get to fill out and you check different boxes like an order form? About the 57As. What does that mean to a pro and what are your other options? 57C 58B? How does the numerical and alpha system work? TGK 231.3? I saw a video of YouTube someone got there hands on a Cilic racquet I believe. What does TGK stand for and the numbers? I heard the .3 means an open string pattern...231.1 would mean a more dense string pattern, maybe I have it backwards. I just really want to learn up on it being a huge Head fan/Safin fan/tennis fan/teaching pro/tennis nerd/etc.
