How do I know I have correct boule size? If I compare all manufacturers suggestions and some suppliers my ball perfect size vary from 72-75 mm. (Handlength and longfinger size guides) I have then considered OBUT is the biggest manufacturer so they have probably some experience, and then it should be 73 mm, but in the lower end handsize 82-86 mm -> 73 mm. (I saw a list where many good male player had size and weight listed , and most had 71-73 680-690) Due to my handshape I think I could gain with 72 but how do I know if that is correct size ? Is there any exercise practice to do to decide with size is the correct one or is it only based on feeling ? I started with OBUT Match 73/690 my first ball in my short career, works ok, but when do a high lob or plombing it releases to early, is it size or technique? Then I tested OBUT RCC 72/690 a used ball, but very slippery, ok when hi loob and slippery when plomb, but shooting miss left, size or technique? Now I got MS Master Inox 72/690 to test, it is a used boule so the surface have good grip. Any suggestions how to decide correct size quickly, so I can drop that mental thought and focus on playing better.
