Carl, I use the 352X bulb in my two Jensen 15 cast base and one aluminum base.  I just find it gives the nicest, brightest light.
That bulb however is not the easiest to find.  Jensen usually has them sold individually, I have bought from bulbtown.com in the past in boxes of 10.  Downside is they tend to burn out sooner than the #14, but the brighter light is a reasonable tradeoff in my eyes.
