Hey Tom,
Personally, if I had to choose between the two, it would be the "G5RV".
I have never used the one you described, but have used one in a situation
where I was waiting on some help to put up a Double Bazooka. I have no
experience with the Carolina Windom, have listened to fellows discussing the
pros and cons of it to various kinds of Dipoles and most of the time it did
not
get good reviews.
My personal choice is the Double Bazooka, however I am not cramped for
space. I do not know your situation in that regard.
