I like hammerhead tips for breaking and jumping but honestly the break shot is 99% technique. Also although you're not using your regular stroke to break, the foundation of your break shot is still your stroke and if you have any imperfections in your stroke fundamentals they'll get exposed in your break shot. Everything gets exaggerated. Any flaws in your stance, mental game, follow through, pre-shot routine, etc will get exposed and will cause you to lose accuracy and hence power. Keep working on your stroke and your break will magically get better. But yeah if you're trying to park the rock center table just elevate the butt a tiny bit, hit the cb a touch above center and go for it. There are so many factors that go into the break shot, this would be too long of a post but a) most likely you're not hitting the rock where you think you're hitting it b) experiment with looking at the rock last ( instead of the object ball ) to gain confidence c) make sure the back swing is very slow, ideally pause before the forward swing. The tip is the last of your worries. Also heavy break cues are generally a no no. Try removing all weight bolts to gain speed ( which is power ), I like my break cue under 19. With the headball break on a barbox even with the wooden rack I'll rarely come up dry and almost never scratch. I'll make at least a ball on the break 9 out of 10 times. Don't try to break with 100% power, there's no need on the barbox. Control is your friend. Also watch SVB, it doesn't come from the wrist like a normal stroke, it comes from your shoulder. A tight grip will really slow you down. etc etc. Also if your playing cue has an LD shaft and your break cue has a standard shaft that might be your answer. In other words you accidentally putting english on the cb and your standard shaft deflects more. Watch your cb if it goes right center or left after impact. If it consistently goes hard left or right you got a major problem you need to work on.
