I took part in the ARRL DX SSB for little over a hour at Sunday afternoon. I'd choosen to be on 20m at around 16:00 UTC as it was the best time according to VOACAP. Propagation was not that good but managed to work 36 USA/Canadian stations. Not bad for 100W and a vertical. I did comparisations between the horizontal loop and the vertical and this time the vertical won with 6 to 12dB average.
