I would think most will tell you, low enough to see over. how ever I ride a gl 1500 se . when riding with the wife on back the wind was beating her up, so I went to the tall and have to look thur. it is unconformable for me in the rain, but I can see well enough to drive. and have in some hard rains. I guess I will stay with the tall. if mama is not happy no one is happy. I use a slip screen tall. it slants back and is a head knocker until you get use to it .
