Start with your drives.....
Hit one with full back spin and a tail wind, then when you get a similar wind strength/direction, hit it with no spin and see the difference for yourself...
Too many variables to type here..
When to use TS / no spin 98% hit for a bounce n run / 3/4 spin to get under \ over a tree...etc etc etc..
Play around with different spins, a useful tool when you know what spin will do what to the ball flight.
