Topband: FCP versus loaded or "T" radialsradials

I had an inv L with two FCP radials. The radials were not in an optimum direction. And I had a difficult time working NA, i.e in the direction were I did not have FCP radials. I had the impression that it was not an efficient antenna. This season I installed a 21m/70 feet tall toploaded vertical with abt 25 ground radials evenly spread out. After that I could work all directions, and my signal was as well much better RBN wise. However, if you have space limitations, I would definitely advise trying a FCP radial system.
