I found an example of what the tenuto markings sound like: (the rising triple a few seconds in to where I marked this off, like 19'22")
https://youtu.be/VYBQyOOED8k?t=1160what effect exactly do you want?
it's very difficult to say because you started out describing two things that are in and of themselves contradictory.
how fast is the excerpt?
how fast will those 16th notes be?
a slur will make the 16ths VERY, well, slurred. it's a single bow stroke, the fingers alone give the note changes.
if you simply leave them unslurred, then each 16th note will receive a distinct separate bow. this can still be "legato" but will more than likely be played detached instead. again, tempo, dynamic, and context will decide.
a slur with staccato marks indicates a very specific intention (again, depending on the tempo).
if the run is fast, it will be played upbow, and will have the bow bounce on the string creating a very particular-sounding staccato. if the run is slow then it will be played in a single bow, but the bow will briefly stop at each note.
is the dynamic soft? loud?
is it a solo, or a sectional?
slow? fast?
is it meant to stick out as far as the articulation is concerned, or is this just a "slide" up to a more important element?
answer all of the above and we can probably find the best articulation for this particular excerpt.
