Not bad.

Perhaps if I do this as a first step then apply a 7th or 8th order 
butterworth filter I'll get the best results with least disruption of the 
signal?

IME, you've found a good direction to go in. Experiment with fiilter types, 
(butterworth, Bessel, Chebychev), order, and corner frequencies.

IME the worst thing about the FFT filter is that it can't be controlled well 
at very low frequencies.
