These are great game improvement clubs. They hit very straight and longer than other irons. The lofts are stronger than other clubs so they hit farther (XD = eXtra Distance). I've been hitting them for several years now and although I've moved up to a new set I like them so much I'm holding on to them just in case!
Not as precise but these irons work like a sling shot. One club extra distance from these irons.
