Trinidad Undisputed Yuki Yamada Model Gomez Type15. As before, the soft and steel tip models are meant to have the same throwing feel. Without changing the specifications from the previous work, the soft tip model has a long and gentle change to the rear tapered part, making it closer to the feel of the steel tip model. The central part of the barrel has been changed to a simple ring cut only, and the stronger ring cut is placed only in the rear part that grips with the main one.
