Another Tip Question

I read somewhere that you should chang your tip often and its better to have it done by a pro.
How ofte does this need to be done.

I'm using Triangle tips and I believe there considered a hard tip.

This forum is better than a pool hall all I do is type in a question and
zap you guys give me the correct answers.
Thanks

1. you don't need to change the tip often, it should be replaced when it lost most of it hight and it's close to the ferrule. how often is that?, well it's up to the hardness of the tip and how often do you reshape it.
2. It should be done by a pro so the ferrule will not be damaged in the tip replacing process.
