I must be a banger

. I've bought a large number of shafts, and many come with an everest tip as the default. I never liked any of these tips. At best, the very best, it's like an inferior Moori M (which used to be my go-to). It would have no spring to it, just dead and dry. Comparing directly, side by side, you'd be shocked at the difference. Of course that was some years ago, I don't even know if you get Moori M's anymore and what their quality is like these days. There is one caveat, and that is that I never once purchased an Everest and put it on myself, so it could be that the professional installers did something to them or that they were old when I got them.
At worst the Everest suffers from every problem a layered tip can possibly get and for me they tended to be ruined rather quickly. They would glaze, delaminate, you name it. Keep in mind I would play every day, sometimes for hours and hours on tables with dead rails where you had to stroke the ball to get around. If I had to choose between an Everest and a Triangle, I think I'd take the Triangle, if I could try a couple of them (which should be possible due to them being so cheap, and that I put on my own tips).
The Tiger Sniper tip was IMO the best tip they made. It had some springiness to it and seemed to last longer. A little on the soft side perhaps, but not too bad. I'd take that over an Everest every day.
Personally I use soaked and pressed lePros only now. I think they're more predictable and I have IMO perfected the process of getting them exactly to the hardness and feel I like, which is a bit harder than an Everest. Of course, every once in a while a LePro turns out to be crap, even after being soaked and pressed, in which case you cut them off and put on a new one without shedding a single tear.
