The bulletproof tips are made of bulletproof glass material (at least that is what I remember reading about their whole marketing thing), which I am 95% sure is polycarbonate plastic.
They hit just about like phenolic tips, was not a fan.

It don't mean a thing if it ain't got that ping.
Basically chalk is abrasive, it gets pounded between the phenolic tip and phenolic balls. The chalk can actually get embedded into the CB surface, like a tattoo, it won't come off without enough polishing to reduce the diameter of the CB.
A phenolic tip leaves the impression of the chalk grit in the surface of the cue ball. A leather tip does that much less, if at all. If your game is such that you're fine with a cue ball with a sanded surface, then it is not a problem.
You have to know what to look for and how to look for it.
It does make a difference.

Why do you think it is good to have less contact time on the cue ball?
I can confirm that cueball will take damage from phenolic break tips. We had 2 new sets of Duramith and many people are using phenolic tips and now over time cueballs start get bad and need to be replaced soon... I actually used my playing cue to breaking due that and took out phenolic what came to my breaker and changed it.
It appears White Diamond break tips are the answer for those wishing to have a tip harder than leather that would be safe for a cue ball's finish. I've been using the White Diamond for about a month now and am very pleased with it. In all fairness, I have no idea what it's made of.

Water buffalo hide tips are really hard, consider those as a replacement
According to my current understanding of squirt, it is essentially unrelated to tip contact time for any normal contact time from soft leather tips to phenolic.
Check Dr Dave's website. He did an experiment on this. This is a quote from his website...
"Another set of more careful experiments documented in the Cue and Tip Testing for Cue Ball Deflection (Squirt) video and “Cue Tip Squirt Testing” (BD, June, 2014) seem to imply that tip type, hardness, and height have very little effect on shaft squirt. Among the wide range of tips tested in the video, the harder tips did result in slightly more squirt. This makes sense because the harder tips are denser and heavier, creating more “endmass.” The shorter contact time seems to be less of a factor than the added weight."

Many have said that unless yo can really smash the cue ball you don't need phenolic. Most likely true. I have a phenolic break cue. It is easy to miscue, but for the most part I get good action. Better action? With my milk toast break probably not. Anyway, I spent the money so I use it. I also don't want to wear out my regular playing cue.
The half moon marks that appear on a cue ball from a phenolic tip, in my opinion, are generally the result of a high velocity break attempt combined with an off center hit, but not necessarily a miscue.
As I clean / polish all the sets of balls (brought out and used exclusively for our 9-ball tournaments) the following morning after our tournaments, including doing the cue balls by hand to remove the miscue marks, I’m noticing some half moon permanent scars showing up on our new red circle cue balls. This is the only thing I can attribute it to.
Could the red circle CB be softer than other CBs?
Do you think (since they're u shaped), it could be from jumping?
no
I changed a few missing tips in the clubhouse. Did one piece tip ferule combos. One was a white g-10 and the other was polycarbonate.
How much damage can these 60-80 year old guys do. They seem to like how they break

There are a number of factors to consider. Relative hardness, velocity of the cue, mass of the cue and contact area are the major ones.
Not all phenolics are made the same. Often plastics like this are reinforced with glass or mixed with other plastics, so you can have mismatches between cue tip hardness and phenolic ball hardness that may result in scratching the cue ball surface. For a polyester ball that is much softer, it just becomes almost a certainty. I suspect that is what might be going on with the G10. The last time I tried an experiment to find if there were non-organics in a product I tried burning it and weighing the results. It just made a mess and didn't resolve anything, but I would almost guess that the G10 is glass reinforced.
Scratching or dinging the surface is not the only way to damage the cue ball. If you have a very high velocity and high mass, hence a large kinetic energy transfer, a slight miscue where a sharp corner of the tip impacts the cue ball on a flaw, you may very well chip the cue ball. The kinetic energy transfer at that point will be converted to heat and a shock wave, so you may have momentary local temperatures of several hundred or a couple thousand degrees, enough to deform the plastic locally or maybe chipping it, depending on if you happened to hit a micro crack just right and fracture a piece (local stress is inversely proportional to square of the crack or defect diameter, basic fracture mechanics). For local temperature effects, note all the burn marks near the head line from cue ball acceleration on breaking.
Can you shatter a cue ball with a tip of equal or lower hardness? Think lead bullet and hard pool ball, so yes, but it is unlikely that any human can achieve those velocities. If there is a flaw in the ball, maybe, but I sure can't hit that hard. Might be an interesting experiment to do with old balls, an air gun, and some semi controlled condition. I've got boxes of those I would willingly donate to the advancement of science.

I tried the White Diamond for a while. It was better than the tip it replaced. I wanted to love it, but I felt like I had less control, and I couldn't get into the feel of the hit. I recently switched it out to a Bulletproof tip, and I am loving it. To each his own just like the playing tips.
you an engineer or just stay at Holiday Inn last nite?
