Which is the best make of plastic trainer bit

[Jazz18]

I've just bought a young 4 year old and have been advised to lunge with a plastic trainer bit. I wondered what make people recommended ? Also would it be advisable to ride on one? I'm currently in a loose ring turtle top neuschule snaffle.

Who is doing the advising? If it's your trainer why not ask them.
If it is a random person do they know your horse?
Nathe type bits are ok to ride in but if he is right in your current one why change?
