I have seen a few tests done on shafts. Some with robots, some by a person. I am always asking good players what they are using. Most say whatever came with my stick. Some have changed tips. So most are standard shafts and not low deflection. Or at least not advertised as low deflection. These players play lights out and can pretty much do anything they want with their cue. I do understand stroke is probably their greatest piece of equipment. Guess my question is this. What is the best method to test deflection? Who actually tests their stoke for deflection before jumping to a low defection shaft. Are super soft tips good or bad for deflection? My understanding was you wanted a harder tip for a straighter shot. When does their become a sacrifice between aiming and English? I know I really need to work on my stroke to become better. Guess my biggest question is. What is scientifically correct? I believe equipment can help and hurt your game. Where is the fine line? Take away preference and opinion. Nickel or dime tip shape. It can all be confusing.
