Not really sure which side is right (lite & fast or slow & heavy) since both sides present good arguements for their point of view. Today it seems to be lite & fast. Several years ago it was slow & heavy and before that, it was lite & fast. Since I have no first hand experience on this matter, I go both ways. I alternate every other round between Win SXT 147gr & Cor-Bon 115gr. Share what you know, learn what you don't -- FUD
