Albeit that all these inter-changable thumb systems are becoming very popular I do not want to go this route. Instead I would like to explore the area of thumb molds. A bowler I know from league uses thumb slugs made from a thumb mold. Can anyone with experience with these thumb slugs made from a mold of a thumb from a ball they really like explain to me how they work. Can they work with thumbs that are drilled oval and if so how do you ensure that the oval is set correct position when inserting the molded thumb slug into a new drilled ball? Also how are the pitches effected? I've heard of the ultimate thumb mold system through buddies. Anyone have any experience with going through them to do this? Thanks in advance for input.
