Correct semiquaver notation

[perfect_pitch]

Which of the following examples is the most appropriate way to notate semiquavers, in this instance?

To me, the first one does look like a more traditional example where you have to fill the start if the beat with semiquaver rests, however the second one to me looks much nicer, and far more convenient.

Is there anything wrong with EITHER of them?

In the first example, presumably the intention is to hold the lower notes through each group; in the second all notes have equal duration. It depends on the required effect. You could always put tenuto marks in the second.

Thanks ted... I'm doing this by ear, so I'll have a think about how I want to notate it...
