You will forgive me if I complain that this is getting a little tedious

I re-tested them yet again... they are essentially clones.
The basis of the test was the 3w. The Titan, Zeus, Hestia 3w clubs are all 14° loft.
The Zeus/Hestia come pre-fitted with +1 skill, so you would expect them to be .5-.8 yards longer due to this +1 skill.
The Zeus swing bars are a little faster than the Titan swing bars. The Hestia swing bars are a little slower than the Titan.
I tested all 3 clubs with the same stats.The in-range stats when hitting them were:
Titan 40 P, 55 I, 339 S
Zeus 40 P, 55 I, 340 S
Hestia 40 P, 55 I, 340 S
The range temperature was the same at 25°. The hits were all identical, both at the 100% pixel on the right, and the 0% pixel on the left. Any hits that did not hit the perfect pixels were rejected (not used). The average of 4 good hits was used. Full side was used for all shots, by using SHIFT-<RightArrow> 5 times.
The Zeus/Hestia 3w distance was 582. The Titan distance was about 0.7 yards less.
Testing requires patience and care, that you are using the same stats, the same hits, the same temperature, and the same spin. I have found that when people get odd results, it is because they were not very careful in the range. Just hitting a pixel or 2 off at the 100% area can vary the result by 2-5 yards. Also, you need to average 4 or 5 hits, since shots can vary by 2 yards just from the 98%-100% tee condition.
