[Antennas] DCTL questions

The DCTL antenna - it's really a half-wave loop, right? But with continuous
capacitive loading between the two identical loops, it is shortened to about
1/8 wave total loop length ( with about 1/4w worth of wire, total. )
I read an article by someone who built 2, one using twinlead, the other using
ladder line. But unhelpfully, the article does not say another word about 
comparison of the two. This article is posted on the net. I wrote the author
to say that if his conclusions were negative, he should title his article "Do
Not Build this Antenna", instead of describing how-to. 
Anyway, my questions: Since the antenna depends on continuous
capacitive loading, it would be best to use twinlead instead of ladder
line, right? Also, the 2 stubs: the tuning stub could be replaced by
a high voltage variable cap, right? And the shorting stub, probably
with a coil transformer for impedance matching?
