Forgot one detail in my post. I'm using an SSR and a digital controller set up to fire it at one second intervals.

The lack of temp swings with the tighter control is supposed to prolong element life 400 times in the case of an SSR and up to 4000 times with SCR control. I'm sure these numbers were achieved somewhere more element friendly than the glass environment but you get the idea.

The best electrical heating stuff I've seen on the web is at Watlow's site and you have to search around for it because they keep moving it. It's called The Watlow Educational Series and has THE BEST explanations of all things resistance heating and control with pros and cons and simplified explanations.
