@JohnBAngel I think you found your solution. That is what I do. I also had to adjust my music stand for my cello, but for a different reason. I had to raise it so I would sit up straighter when bowing. But, solution is similar. The music stand where it needs to be for you. As Stringy said, memorizing the music helps, but, I cannot always do that and never while I am trying to get the bowing right. I place the stand for my bowing viewing, like you, when I play my violin or viola. I place it for my posture for cello. 

It is funny with the cello. If I already know a piece, or figured it out myself, I naturally sit up straight, but if I am learning it and/or struggling with it, I tend to keep bending down and getting right into my cello. Raising the stand has prevented that because I have to look up to see the music. My instructor told me to do that because he noticed it.

So, put the music stand where it helps you. I think that when we get more at ease with the instruments and better, we will have an easier time memorizing it. Until then, put the music where it helps the most.
