I can get away with a slightly bad stroke on long straight shots with my 12.75 mm shaft but will miss with the 11.5 mm if the stroke is slightly bad.
That has nothing to do with the shaft itself - see this post for details:

I find that to be true with my 10mm tip.Maybe it's the increased visibility you get hitting the cue ball with the thinner shaft.
That seems to contradict what you said first above.I feel I have.a better chance pocketing a long straight shot with the 11.5 mm than the 12.75 mm.
Anyway, are you saying that if you hit the cue ball the EXACT spot for a spin shot, the thinner shaft will not give you more spin assuming the same tip curvature as the wider shaft?
Yes, that's right. And even with different curvatures the difference is too tiny to matter.Exactly what he's saying.
But I don't agree with this - for the same reason a thinner shaft will not give more spin. They're essentially the same tip, but with a tiny outer layer removed for the thinner shaft - that means the thinner tip's outer edge is closer to the tip's center, which would suggest the thicker tip should allow you to go further out before a miscue. But neither tip allows that.A smaller tip WILL allow you to go further out before a miscue.
