Obviously this completely depends on your value of the miles in cash terms, as to make those bigger savings you would have had to have invested more in the first place on WT+ tickets.

If your flight is a long way out and WT prices are still not bad, it may well be worth looking at cancelling your redemption tickets, booking revenue seats and saving the miles for a nice cheap WT+ fare that you can then upgrade to get a nice full, flat bed business service!
