Yeah, Pantherman, it takes a little practice, to get the feel of it, to move at just the right moment. And sometimes, I'll warm up (pun intended!) with some practice pieces, before I get the results I want.  But it's a skill that's definitely worth mastering.  I use stretched sprue not just for antennas, handles, etc, but fine stretched sprue is useful to fill some seams and gaps.  I like using it instead of putty, if possible, because I like the idea that the seam or gap is homogenous material.
