After my first post I re-read that you were breaking regular flex and stiff flex shafts. You can break a regular flex shaft across your back by swinging 90 mph or even less. Some stiff shafts only take a little over 100. Trackman may help you find a shaft that will give you the best performance but until you stop hitting yourself it will be hard to keep them from breaking. Good Luck!

@Rookie I agree. I have seen both scenarios. Your way is probably more common.

I have had the same problem. I broke 4 driver shafts and 2 3 wood shafts across my back last year. (All about 2" out of the grip). I broke a lot more than that by the Housel but that was because they were used shafts and were probably damaged when they were previously pulled. (the ones that broke closer to the head has nothing to do with the shaft hitting across your back) I have never broken a steel shaft but I do not take much of a divot, if any. The only fix I have found is to use extremely stiff shafts. They do not flex as much so they do not break as easily. It really has nothing to do with swing speed though. The first time I did it I was only swinging around 120 and it was a 2X flex shaft. The shafts are just not made to slap across your shoulder and back like that. You can start using 3X or 4X shafts, or just get used to replacing your shafts. You can still break the stiffer shafts, it just usually takes a little longer. Some of the stronger ones that have found are the USPG - Black Ops LD shafts, the heavier House of Forged shafts, and the UST Proforce V2 LD shafts. The Banshee LD shafts are pretty good as well. Sure, you can always learn to stop your swing before hitting yourself, but what fun would that be?

I know this discussion is mostly about actual golf but I wanted to share my round of simulator golf. I hope no one minds. Played Red Rock and shot 4 over. I was 6 over after the first nine and shot 2 under on the back. Too bad I have not figure out how to do anything close to this in real golf yet.

I did not counter weight my driver, but I did add about 40 to 50 grams to the head with lead tape and it has worked great for me. I have a faster, more violent swing and this was the only way I have found to help me control it. It did take a few try's to get it located correctly. For me dead center on the back side with a little bit heading down toward the heel was what worked. I actually built a very light weight jumbo grip so I guess I did the oppisite of counter-weighting and I have been hitting farther and straighter than ever. Side note. Since this worked so well with my driver I tried it on other clubs and it did not work at all.
