Lines between dots approach: efficiency question

Hi all,
I’ve got a question about the efficiency of two functions I wrote that do the same thing. I’m trying to figure out which one to use. The functions draw lines between a series of points, and continually redraw them as the points move.

The first function uses the drawing functions in flash.

The second function creates an empty movieclip and draws a short line in it, then uses trig to scale / rotate the movieClip to make it fit between the dots.

Both work, but as my program gets larger I’m wondering which function would calculate faster. Any thoughts?
