Congrats on testing it, but I think there are too many uncontrolled variables in this test to give meaningful results. You can't tell (from what I see) where/how hard the CB was hit, where the OB was hit, exactly where the CB/OB were located, to name a few.I did this test with a friend one day, we happened to have about 8 different shafts between us on different cues.
We played a low right-spin shot off a rail to see how far back downtable we can get.
See my caveman like picture of the shot, the solid line vs broken line was about what we got from different shaft and tips combination.
Least spin to most spin
Standard shaft, 1 layer tip - solid line
Standard shaft layered tip
LD shaft, 1 layer tip
LD shaft, layered tip - broken line
Going from each of those got us another half diamond closer to the corner pocket on that shot. Note this picture is a rough setup of what we did, not exact ball placement.
We each shot with each combination 3 times, so 6 shots per shaft/tip combination which would be good enough to remove any sort of stoke inconsistency. We were both pretty consistent as to where the cueball ended up with each shaft.
