Yep. That's the company line right there. Other then them telling you so where's the scientific evidence to back it. Because the eye test is giving me the same results.
No it's not just a company line. Most things related to cues are very subjective .. having said that.
I recently purchased Mezz PB2 with DI Pro shaft. This is the best break cue I've ever had. The combination works for me. It's very well controlled break with a power. It doesn't seem to be that important for me for 9 ball break (where I use my playing cue to break) but it seems to make a big difference in the 10 ball break from the middle to open up the rack and get the whitey under control.
If others can use sneaky or other cues to break, great for them but for me this break cue made a difference. PB2 is also great in the way that I can make weight adjustment by just removing some rings depending on how I fee that day. Now, is the difference worth the price?? That's up to the person. It's almost like asking "why would anyone pay more than 199.99 for a cue?" type of question.
