the main disadvantage of a G10 pin I see is only from cue repairman's view: if there is a need, for any reason, to remove the pin - it can only be broken and drilled out, while metal pins are often removed with the help of heat. G10 doesn't transfer heat so it makes no sense heating the pin.
I can't exactly disagree. Mass at the joint will definitely influence a cues natural frequency - with increased mass there is more damping.
So lets say two cues are as identical as possible with exception to the joints.
-Cue A is fitted with a .9 oz. stainless pin, a 1.6 oz. stainless collar, and .35 oz. brass insert. Total weight of the these parts on cue A is 2.85 oz.
-Cue B is fitted with a .16 oz glass pin, a .12 oz. phenolic collar, and 2.57 oz. of tungsten is added behind the pin. Total weight of the these parts on cue B plus ballast is 2.85 oz.
The natural frequency of both cues should be equally damped ...but the materials in the respective joints should also store and pass energy differently, and as I understand that's where resonate frequency comes into play.
I don't pretend to have any idea how much variance would be found, just thought it would be interesting to compare the numbers.
Kim, my main points were that with the right equipment and a sound methodology it should be easy to separate fact from fiction ...I was actually trying to solicit something other than opinion.
something like a wooden pin???I don't know why that would be a disadvantage .
The steel pins have the disadvantage b/c they cannot be machined out easily.
Heating pins to remove them is not an advantage. Heat is not good for the wood and glue.
Removing G10 pin is much easier. You just cut it off then drill/bore/mill the rest .
I mill them out cleanly then re-plug the hole with a threaded 1/2 20 matching wood dowel.
G10's big feature was mentioned by RAT. It lets the cue resonate unlike other pins. It's the closest to one-piece cue feel than any other joint screw imo.
Biggest disadvantage is, it is a little abrasive.

There are many opinions about G10 pins. Most opinions about G10 is subjective. I have not seen any scientific proof one way or the other.
G10 pins seem to be more abrasive to the threads in the shaft. Some people have trouble with them loosing up while playing. If they flex, then I don't want them. I don't want any flex at the joint connection.
I will stick with metal pins.
that's my opinion

I have also heard about the abrasiveness of G10. Do they actually slowly grind the wood in the pin. Does anyone have experience with G10 pins losing their grip. I have looked at Cog cues and would love to know more.
