Hi Lisa,
We were in the same boat as you. Hubby turning 45 so we needed 8 in each band to get us the points needed for 190. He sat the Ielts 9 time and always missed by .5 in only one band each time, he scored 8.5 overall but thats not good enough it needs to be in each band, it was very demoralising for him. In the end we went for the 489 which we received last month. Just grateful to have the option.
Go for the visa that best suits you and puts less pressure on you
All the best
