can you recommend training/practice balls?

[bentCue]

I sometimes see coaching videos with specific training balls. Balls with hit patterns, dots, lines etc

can you recommend the use of such training tools?
and if yes, which ones would you recommend to buy?

cheers

I can give you some personal advice on the ultimate training ball by Nik Barrow - you will spend more time setting it up than you will actually potting balls! its great to identify obvious errors in alignment, but that's not very often and can be fixed with solid basics

[bentCue]

oh yes, I believe that.

these one look interesting, but they are very pricey... and i am still not sure how practical they are in the end.

60 euros! Wow.

The ball in the middle with the black strip down the middle looks useful. The others just look like poorly thought up gimmicks

It’s all badly thought out rip off gimmicks .Practice potting balls in the middle and screwing back to the opposite pocket
and practice potting straight balls in the corners and following the white in from different distances ,that’s as good as you need to get it .

yes, good advice.
ok, money saved
