Things seem to have strayed from the topic. Absolutely nothing wrong with a 3 element beam. I'd pay attention more to the time difference. When are most operators on? Morning and evening, but not always.
If you have a good dx predictor, you can use that to help. VOA Prop is a great little program, and 10 meters is close enough to 11 meters to give you a good idea of where DX "should" be. Funny thing is with propagation, I've found I made the trip on my A99 better than I could on my 4 element Maco. That has been both to Hawaii and to Australia. You just never know what polarization is going to do after it flips and flops a couple of times via propagation. And the path that it gets there can be odd too. I turn the beam for strongest white noise, and often times can hear stations that I "shouldn't" be hearing. Like pointing northwest from Texas got me to Australia stronger than by pointing at them. So, you might find the "long path" works better for you than by pointing across the US. VOA Prop shows you long path, too. Just keep trying!
