I would heartily recommend stretched sprue. If nothing else, it'll save you the grief of having to drill holes.
It's easiest with a pair of gently-gripping cross-lock tweezers. [If they grab too hard, they'll kink your line when you pick it up.] I measure out my lines, then pick up the line with the tweezers and dip one end in a little puddle of white glue, then touch it to the funnel location, You can then "swing" the free end into position (a toothpick is handy for this), apply a tiny dab of the white glue with the tip of the toothpick, and nudge the line end into the white glue. The white glue shrinks as it dries, and dries clear, so usually no touch-up or painting is necessary. An added benefit is that if you need to move or replace a line for some reason, you can just "pop" the end loose with a gentle pressure, or moisten the join and it will loosen after a few seconds.
If you pull nice straight runs of stretched sprue, your lines will look fine as is. If you need to tighten lines a bit, I've found that lighting a toothpick, then blowing out the flame, will give a great tiny ember that will tighten the sprue lines nicely. The white glue is quite strong once set, so pulling loose when tightening lines is rarely a problem.
