I've had my F12 C-4XL (previous model to the Delta 4-XL)
up for a couple of years. So far, zero issues; I'm VERY
happy with it. OTOH, I've read multiple accounts of fried
inductors in the olde CC shorty fourty. Apparently, the
current XM240 is OK.
I went with the C-4XL because it was available for half the
price of the current F12 40/20/15/10m offering, and I could
not find any significant reliability and/or performance issues.
In fact, F12 said it works on 17 & 12m using an ATU. It does.

I do believe that the coil loaded Shorty 40's (F12 or other) are a much
better choice than the linear loaded versions. I think that W8JI wrote
a piece on that once ... maybe it's even on his website. I have the
Optibeam OB2-40, which is a coil loaded Shorty 40 similar to the F12
antenna except much sturdier, and it works great (yes, I've measured the
pattern).
