Tips
There are as many combinations as Carter has pills (yes I am old). Since you contact the cue ball with the tip (duh), I suggest you choose wisely.
The ferrule makes a lot of difference as well. Again, thousands of combos.
After MANY years of dif combos, I'll give "MY" opinion(for what it is worth),I played wih LePro tips for years. Then with Triangle, both of which vary considerably in density & hardness.
I have found the layered tips to be considerably more consistent from tip to tip than nonlayered tips. Tony at Black Boar has a hardness tester to test his non-layered tips. A layman does not have that luxury. I currently am experimenting and using Kamuii tips with quite a bit of success.
They are very consistant from tip to tip. They cost more than other tips, but they last a long time. I build cues, and have been playing good pool for 35 yrs. A thread above me hit the nail on the head. Experementation costs money. But knowing what works BEST is up to you. All the decoration in the bottom section & 30gpi shafts is all for naught if you can't control whitey. If you want to play good you need the proper eqipment & the tip is the most important. ( I think this is more than 2cents worth)
