Short game book Phil Mickelson or Dave Pelz?

Id go for :

Pelz for the first 100 pages for the insight into, and importance of the shortgame. I wouldnt rate the rest for the average golfer. Less technique oriented, too mechanical, and I dont think the multi wedge, clock face, know all your yardages, process can be used without pro level time dedication.

Phil is a very good general read for the average golfer, simple, and I think offers good improvement propects and a good range of shots with simple technique ideas.

Utley. Didnt press me. Maybe an alternative to Phils book that might suit some, but Phils was the clear winner of the two for me.
