Mark, similarly to Richard I settled for the position shift. The main reason for me was that with the 3rd position bar it was very difficult to get back to first position to play the F and D clean and in time. With faster tempo, bar 11 is already somewhat difficult in that the RH needs move up quickly to play the notes on 4th string. Having the left hand position shift at the beginning of the measure just made it difficult for me to keep the form, as too many things seemed to be happening too quickly. Although the two rapid position shifts were more difficult than the 3rd position bar, they give me more time to prepare for measure 11.
Richard, thanks for your comment! I tried the 3rd and 4th beat notes both legato and staccato, and ended up using staccato as it sounded better to me adding some percussive flavor. As the name of the piece means "dance of the axes", the staccato in my opinion added some atmosphere of danger
I also dislike playing long melody notes on open strings, as I cannot do any pitch modulation on them ("vibrato" may be a bit strong word in this context). I guess this is a matter of opinion, and I also confess that I did somewhat sloppy job with the staccato. It sounded like I wasn't paying attention at all to the duration of those notes. I should have been more clear on my intentions, and do the staccato more sharply, or alternatively go for full legato
