Could someone please explain what exactly is meany by a durometer tested triangle?
I agree that feedback is probably the most important thing when it comes to the choice of a tip.
I think Hideo Moori has taken a lot of time to make sure his tip does not delaminate. One can spin this tip and apply a lot of heat to it and it will stay intact. The down side is that it does not hold chalk very well.
With the Sniper, I like the fact that it holds chalk better. I think it is a tip designed more toward playability than delamination resistance. It has a very different hit than a Moori in my experience.
I have never tried the Kamui, but from what I understand, they are also geared towards delamination resistance as their first priority.
I think there are trade offs. Please correct me if I am wrong, this is what I think: When a tip has more layers, it will have more glues. If you use very thick glue, and use a lot of it, chances are the tip will not delaminate as easily, but the glue might cause miscues. More layers may also help to prevent mushrooming, but it may compromise on playability as the feedback might be muffled. So, I think a tip that plays well, may not be the tip that is the most durable against mushrooming and delamination.
Any thought?
