when you need penetration, you want point A to point B quickly... and point B is where it penetrates the other player.
not to mention, it takes more energy to produce 100/2000 than 100/1500.
Well there is also the variable of where the shot was hit. And where. The angle. The height will determine depth as well., Basically more spin is better as it allows more options most of the time as it is a safer shot.
