I'm just looking for consistency and low squirt. Each time I changed, I think my game improved. First, a 314 (for about 5 years) then an OB Classic (for about a year) , now a Tiger Pro X (for about 8 months).
I have no intention of changing from the Tiger Pro X - it does everything I want, gives precise feedback and I have 100% confidence in the shaft. For my stroke, it's "just right". It took several motnhs to completely adapt to the smaller tip, but I'm sure glad I made the change to tjhe Tiger. I have two and they play identical - the only difference is tip feel.
My game improved because I will play a greater variety of spins with confidence. I don't feel a need to avoid any shot because my shaft might react unpredictably. If I had to switch to a house cue, for example, believe me there are a lot of shots I would avoid altogether.
