I'm 6' 7". I ignored all of the advice and had my graphite-shafted clubs extended from +1" to + 2 1/2". Contrary to all the predictions, I love the results. Everything feels better, and I gained 5 to 10 yards on my wedges and about 15 yards on my longest irons and woods. ... Problem is, on my first bucket of range balls four of my shaft extensions snapped off! No doubt the rest will break any time, and I need a solution. Does anyone make a shaft extension that's as strong as a graphite shaft?
