i personally like the pro v's because i can be agressive with my wedge shots, and know that i am going to get backspin or check. i also like them because i find it easier to work the ball with the pro v.
many people play with open stances because it is easier to rotate the hips through impact. a pro suggested i do it, but when i tried it a hit consistant slices... this might be because of my flat semi-swing though. works for some people, but not for others... best try everything and see what works for you, just like putting.
