I may have mentioned before,but I mainly practice in and around 40 yrds,and every now and then hit long shots.So in saying this,it goes without saying that I hit every shot imaginable around greens,so ,in order not to get too bogged down and lose interest,A couple of weeks ago I began chipping using left and then the right ,it all hit home when I began getting into "plane of motion" in the book,it is a real fun time ,you really learn about alighnments of both arms and most of all...CONCENTRATION...no doubt a lot here have tried....love to hear your findings and results L+R handed
