Should I try to do all the string crossing with a down bow on the D string and an up bow on the G string ( which to me feels unnatural), or the other way around (up on D, down on G) which feels really nice. Doing it the second way, which feels easier, would require me to change something with the bow approaching it. My teacher suggested doing a double down on the last two eighth notes RIGHT BEFORE the string crossings start. I'm not in love with this and would love to hear a second opinion. I also heard someone saying to start all the eighth note runs before the string crossings on an up bow. Just want to know how some seasoned players approach this problem. Hopefully I was clear in my question.
