To each his own but, "feel" is how the energy transfers from the tip to your hand. The more contact you have in the joint, more vibrations make it to that hand giving you a more accurate feel for what happens at the time of contact. This is why the Radial pin is so popular. It boast 97% contact when assembled. 3/8-10 is around 70%, 5/16-14, 18 have around 65%. There is a lot more than just joint contact involved but.....
I have not seen numbers on Uniloc but only a thread and a half makes contact. Yes, the threads are machined in a way to have more contact per thread but it is only a thread and a half. Let's say it is 80% for less than a 1/4" I'd rather have 65% contact over an inch-worth of threads. JMHO.
I am not making an argument for or against any certain pin/insert. Just want to spark thought and conversation.
