You cannot know how a cue is going to "hit" based on the joint alone. This has been definitively proven. The "hit" is also VERY subjective, different people trying the same cue would have different opinions.
As was said, cue "hit" has many determining factors- solid ivory joint with 3/8 10 Pin- Gilbert made a lot of those- I had one once- if you pair that with a stiff taper shaft and a very hard tip it will play different than a 12.5 MM pro taper shaft with a tiger soft or ultra soft tip - so many factors on a cue "hit" you just can't look at one aspect for a final conclusion.
What does "harder" mean here?I've got a 5/16 pin Ivory Joint that hits very good. Its not a big pin but its an
Ivory Joint. Plays harder though when its cold. You have to warm it up with your hand.
The slimmer the shaft the harder the hit. A lot goes into the hit.
Have you ever played with a South West and what did you think of that hit?
My Rick Howard is solid ivory joint and big pin 3/8x10. The old saying holds here too, "you have to try it to believe it".
Gotta admit, a capped ivory joint with big screw has a nice feel to it.
Prone to cracking though .
