I own half a set of Yamato 2001 Tour clubs (5-7-9-SW). This is my first set, and I've only been playing for 3 months, so I've nothing to compare to. I can hit them pretty far and straight (on my good days) and my pro took a swing with them one day during a lesson and pronounced them good value for money. Can't speak for the woods, as I only got the irons (I've added a cheap Palmer 5-wood to my set). I've got a Yamato putter too (Holeasy 109). Feels OK.
