Mark Crossfield and Coach Lockey discuss playing with what you've got rather than forcing something that isn't as natural.
Mark describes how he hits one shape with his irons and then another with his "rinky dinks" aka hybrids. Mark knows the shape he hits with each club and so plays to his strength and doesn't try to force a shape he doesn't naturally hit.
This means he is more likely to hit the shot he is trying to hit.
