Listen i do not think pelz is an evil monster but i certainly question his motives----i agree that even if he could care less about your golf game doesnt really matter if he is delivering you the product----it doesnt really matter whats in his heart if what hes selling is good----ive been to a short game clinic here in chicago---i was unimpressed-----i have his books---yes there is some good stuff in them---i wouldnt say the guy has nothing good to offer----his straight back straight through putting method is flawed in my opinion--the human body doesnt work like that---the putter has a swing plane like the rest of our club and technically i believe you want to swing your putter on plane as well-----do you have to -NO - you can do it pelz's way but you will have to work pretty hard to do so---not allowing the forearms to rotate is completely unnatural---can you learn to do it ---absolutely would i teach that no way---most pga instructors will agree that the putting works on an arc not straight back and straight through-----mechanically it sounds easier but the human body doesnt work that way----however you could learn to do it that way------i dont agree with pelz on his putting method at all---but its my opinion---if you like what hes saying try it out--it could work for you-----heres the problem with going to a golf school---after you get back lets say youve been to a pelz or any other school---eventually something will go wrong and at that point you will need further instruction and it will get expensive to spend the money and go back again and again until youve got it---its not likely one trip to any golf scool will cure you----and as far as working directly out of a book--that usually doesnt work--for example --you read in a book---"you need to take you hands out of the stroke and hit the ball with rotation"(standard 80 yard wedge shot lets say)---now when you go and practicing trying to do that how do you know you are doing it correctly?--- ----what you think is proper rotation may be improper execution on your part---words paint images in our brain but how do we know we are doing it correctly -----my point is you need a good instructor to watch you and if need be video so you can be sure----also you may need to see your instructor more than once---maybe twice or more until you get it----trying to cram alot of information at a golf school is hard to do ---we tend to forget certain things----however if you have the money and you enjoy doing it that way have at it---you can learn from golf schools but its better in my opinion to seek out a good instructor and work with him or her as much as possible until your able to make the changes in your game----whether it be full swing or shortgame-----there are some very good pga instructors out there--for sure-----ask around ---reputations follow people----
