Sounds like reassurance is being sought whether the Avios outlay outweighs the cash.
Quick answer: only you can decide.
If you were going to part with £7k anyway for these flights then yes it appears to be Avios and a 241 voucher well spent if it were me.
If the aim of the game is Avios optimisation then there's probably some slightly better redemptions out there with smaller cash outlay (RFS within Europe during peak travel dates where cash fares are high) but those destinations may not be of interest.
