I just read another post that made me curious about something. What is everyones personal shaft size preference and why? All of my shafts are right around 12.75. For aiming, I'd like a bit smaller shaft but even the 12.75 feels a bit small in a closed bridge for me, since I have big hands. I don't really understand the benefit of a smaller diameter shaft other than having a smaller, more dialed in point of aim. Is there any other purpose to using such a small diameter shaft? Sorry, I guess I'm asking two questions...
