You do not need an efficient antenna to work DX and without a way to
compare it to other antennas you have no way to measure its performance.

K7LXC will not "talk his book" but I will say that multiple unbiased
antenna range tests - including those reported in the K7LXC/N0AX
"Tribander Test Reports" - have shown that the Mosley antennas perform
more poorly than any other manufacturer's multiband yagis of similar
boom lengths.
It's a bit of a stretch to call it a "book" -- it's a well-written,
well-documented engineering report on the well-planned and well-executed
antenna measurements that Steve and Ward did something like 12-15 years
ago. This report, another on companion tests on HF verticals, and N6BT's
"Array of Light" book are all available from Steve's Champion Radio
website, and all are worth far more than what you pay for them.
The N6BT book is really about antenna design, discusses the designs of his
Force 12 antennas, and includes designs for a nice variety of HF antennas.
The only thing it lacks is an editor -- several chapters are redundant.
One of the chapters debunks the inflated gain claims of antenna
manufacturers, showing that the advertised gain numbers for their
tri-banders were 3-6 dB greater than the maximum possible gain for a
monoband Yagi of comparable size.
