Not as precise but these irons work like a sling shot. One club extra distance from these irons.
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!
