Hey Ron, somewhere in a recent thread, SgtBilko and Oldbayrunner have a wind calculator that has some helpful information on wind. I would recommend that as a starter. It's hard to give advice as most people handle wind differently. Some move the marker, some miss the ding, some do some of both. it is hard to tell you what to do. I move the marker and try to hit the ding (notice I said try ) ;) and it's all by feel and experience and isn't necessarily right. I think that is what the previous poster meant by the comment.
Find that thread form those guys and talk to them, they have it worked out.
