Yeah they are very good, probably the nicest feeling irons I've had. Do have a soft spot for my old titleist 690.mb irons that I loved but I certainly couldn't be happier with these chikara ironsFWIW..Chikara irons/wedges are forged by Kyoei, as are heads for several other companies - including Cooper. Kyoei's house brand is Vega. A UK based, ex Tour Van, wedge specialist (ICGolf from memory, but can't find any links) also uses their 'blanks'.
As for my 'brand count'... Normally 4 (occasionally 3) - Adams Driver, Woods and Hybrids - except for 6h/27* Titleist - Cleveland (occasionally Titleist) wedges, Bettinardi putter(s!!), though often Seemore in Winter.
