Toilet water supply line recommendations?

[DewGuy]

Our toilet has a old style semi-rigid water supply line that has started leaking and I'd like to replace it with a modern braided line. Looking for recommendations on a replacement line. What type? What brand?

Do I need to use Teflon tape on the connections?

Also, do I need to drain the tank before disconnecting the old line or is turning off the water supply valve and having something to catch the water from the disconnected line sufficient?


Thanks in advance.
