I just looked at your equipment and you have the same irons just lower level I have noticed to add 5yds to full back spin and subtract 5+ yds to no spin. (depends on wind) You should keep in mind that when you apply BS it will lift the ball higher so you will have to becarefull because it will be affected much more by the wind. And I see your wedges are the best IMO, but you do not need to spin it back at all maybe one dot if you want to be cute with the shot. Front spin will keep the ball lower and roll longer.(use your discretion on it). I have also noticed that you may use back spin but it will still bounce forward so you still need to expect roll out on some greens (practice) hope it helps
Hit'em straight and Long, pjschaub
I should interject that when useing flop,chip, or pitch I will put full BS on my wedges
