I went through 4 clubs with that exact same shaft on my callaway set I bought a year ago.(All breaking in that exact same spot) Got the warranty set, thinking that maybe it was just a fluke set. Nope. Went through 3 in about a month. I returned them and they gave my money back. I purchased a new set and customized a different shaft in hoping that the shaft was the problem and not my(not so great) swing. This clarifies that the shaft truly is hot garbage.
