Hi there,
if you were to commute the phrase 'Níl aon rud buan ach amháin an t-athrú' so say 'Níl buan ach an t-athrú' would it be best to change the 'níl' to 'ní' as in 'Ní buan ach an t-athrú' to make it sound more idiomatic?

B’fhéidir:
Ní buaine go hathrú.

(Meaning is a little bit different)

Níl buaine mar/gan athrú.

Would either of them work?

They would both seem to sound fine, given so much is commuted in proverbs anyway
