ESTIENNE: if anyone is willing too share their knowledge on this it will be appreciated
I use the same club/ball combo you do, Estienne.
Break your clubs down in thirds, or so. The PW, 9i and 8i handle spin much differently than the 7i, 6i, 5i. The 4i and the 3i do their own thing too. Full backspin on a PW (125) into a headwind maxes out around 116 yards or so, sometimes less.That same wedge with top spin and a tailwind will fly a lot longer than 125. The strength of the wind has everything to do with it and for that reason the best thing you can do to start is learn the clubs without the spin.
Use the spin to control your yardage, keeping in mind the effect on the landing. Just know going into wind, back spin stands the shot up and shortens it. How much it stands it up depends on how much loft is in the club and how strong the wind is. . Hence, breaking your set down in thirds.
A high ding rate is essential to success with these irons. The price of their accuracy is the penalty, or deviation, for missing. They forgive halfway decently but the distance suffers a lot when you miss and not always in a negative fashion. Spin exaggerates this, particularly backspin.
Give yourself 20-30 rounds with them without killing yourself trying to understand them. You will develop a sense for them and it will help you a lot when you start adding spin into the equation. CTTH rounds are a good place to learn, where you can restart and play the same shots over and over. They are fun clubs to learn and when you ding them the results are tremendous. GL
