Personal preference. Have played with all 3, plus 11.75mm, no difference other than feel.
I've been on a bit of a shaft quest lately. Wasn't happy with the state of my current 314-2, has been whittled down over the years and no longer standard. Bought 3 shafts in the last month or two, played in 4 tourneys over 5 weeks with each of the shafts, won them all. I guess it's the archer, not the arrow...
That being said, I didn't play my best any of the 4 weeks. I do expect a certain performance, feel, etc. out of the equipment, and as I struggle to get the right shaft and tip combination working for me there are a few shots here and there that I'm missing. But overall it's more about the feel of the shot, and not the actual result, that makes the difference as to shaft width, tip hardness, etc.
