I'd think that if you are hitting 250-270 with your driver, as regular flex graphite shaft in your irons, might be too soft. And as we all know, some R flex shafts are more like senior flex compared to others. I'd recommned you try this photo think again with some S flex shaft irons, and see what you get. Some bending is what you want, but I think you have too much with the R flex graphites you're using. That much bending is goig to be real hard to control. Distance will vary as will ball flight.
