How can we ever know?
I think in time, after trying several tips, you will decide for your self. There are to many variables for a concrete answer to your question. I watched a Tar interview with Efrin and SVB. Efrin said, "Elk Master, always Elk Master and I believe SVB was using a Kamui Brown Hard tip at the time. I would say those 2 tips are at each end of the available tip choices. Either of those 2 guys can beat any one on any given day, with any reasonable tip. I have tried Elk Master and like them after they are "broken in". I have tried a medium Everest and liked it. I did not warm up to the Onyx my buddy loves or the Zan, probably just me. For the last 2 years I have been using Kamui Black Soft and Medium tips. I will probably end up with the Kamui Black Soft once my last 2 Kamui Black Medium's are worn out. Point is it has taken me 2 years to decide on which tip is the best for me. I think I could of stayed with the original Elk Master. Nothing wrong with trying new tips, most of us here love the game of pool, so it is only natural for us to be searching for the right "equipment" to better our game.
