There is a point where it gets to be too much. I think I'm there now. Ever since I got my Vectrix about a month ago, I've been shootingabout every 3 dayson average. I guess that isn't all that often but when I do shoot, I'll go at it for 1-2 hours. Like someone else posted, I too am beginning to "jack up" my shoulder. Hopefully cutting the time to half an hour each session might not be so hard on the shoulder.
