hi
go for the low running shot and not the hight cut shot, the low running shot is just like a long putt and most high handicapers can play this shot over and over and get it to 3/4 feet of the hole. use 7,8,9,wedge and find out how far each runs for you, will save you lots of shot round the green. also look at gregs chipping lessons as he has a lot of tips there. one other thing, there always dave plez short game bible the packed with drills to do.
hope this helps
