I would seriously consider not having the line snag so much. It gets to the point that it's irritating and some times very unnecessary. I've gotten snagged in 15-20ft water at the top well away from the shore. (no vegetation even shows)
It's kinda funny - you can get snagged in open water as you mention. You can also throw a crankbait or other treble hook bait into thick grass or lily pads and never get snagged at all. This is the kind of "duh" missteps that really holds back what could be a very good game.
