Indeed.  

I'm switching to the later circuit.  CE went to some trouble to switch so I figure it's worth it.  There are a couple of caps to fool with in that circuit.

When I get to this (not today, that's for sure), I'll let everyone know how it goes.

I use my wife's hair dryer and a frequency counter and can quickly stabilize most circuits.  Hallicrafters had a wonderful circuit using a differential capacitor, allowing you to dial in the compensation required.
