Yonex Arcsaber Series

Arcsaber is the Yonex control line, built around holding the shuttle on the string bed a fraction longer so placement is repeatable.

Even-balance frames, and the usual answer for a player who does not want to commit to power or speed. The Arcsaber 11 in its various generations is one of the most widely recommended all-round rackets in the sport - if someone at your club plays "everything reasonably well", there is a fair chance this is what they are holding.
