A word on the spin with those. It is most effective when you think of it as an adjustment for yardage more than how it makes a shot stick. If you know the carry of your clubs you will be able to control what happens after the ball lands. This is where you'll notice the biggest difference over the balls you're using.
For instance, if you had a club that carries 175 and rolls another 5, back spin would stop it at 175, partial back spin would slow that 5 extra yards down to something less and top spin would add to it. So just with partial spin you can control your yardages. Elevations and wind are additional factors.
Head winds are great stopping winds for approaches with partial back spin. I say partial because everybody likes to jam that ball dot down to the bottom and play from there, envisioning that marvelous dart 2" from the hole. LOL. Fun to dream about but let's get real.
Full back spin puts you in turbo mode where any mistake is exaggerated. Miss the ding by a little and suffer a lot. (<----source of a lot of rants.) This is where partial spin is your friend. Clubbing up and using partial back spin really takes advantage of high loft clubs like yours. The wind stands it up and it plops down. The back spin knocks the yardage down and stops the ball. The trick is to know the numbers. :-)
p.s., Courteney made a comment once about shots with top spin fall more than ones with back spin (paraphrased.) I've since paid attention to this and she was right.
