It occurred to me that I could stuff as many as five drivers at a time into a bag, thereby having the ability to test all five under identical wind conditions. This might be too much of a good thing. There's no way to save a game in practice mode, and I don't have the attention span to chart 100 dinged shots in one sitting (it would take a few hours). I've also found that if I leave a game idle in PM I tend to lose the connection within 30 minutes. If I'm going to do five clubs at once, the best I can do is a tiny snapshot. of 5 dinged shots each.
I apologize for the rather messy display...too many shades of red (should have used cyan, magenta, yellow, black, and white). Each line is drawn from the landing point to the end of the roll.
The most important thing to know is... this test is almost completely worthless! The 5-shot samples are way too small to have any meaning. The Big Bertha 9.0 produced an incredibly tight grouping L-R, but when I took a few more swings "off the record" (I'm considering a purchase), the second shot went right down the middle of the fairway (just inside the R1 outlier) and the third went 318-338, the longest shot of the night. Also, the SLDR popped two miss-dings that carried around 314 and rolled to around 330. There are all kinds of possible outcomes that this test didn't catch.
I used the same middleish spin (shown) for all the drivers. It could very well be that each driver has its own unique optimal spin setting, another reason why this is by no means a definitive test. Ball is the L61 Nike.
One interesting thing that cropped up is the roll-to-carry ratio. All of the drivers got more roll after shorter carries. It could be due to a different slope in the landing area. The BPB 10 fairway has a consistent mild upslope, but even a tiny change to the slope might be enough to produce these results. It could also be that spin (and trajectory) has a random deviation component the same way as L-R angle and power. This warrants further investigation.
