Recommendation for tank bag to fit 2007 FZ6 Fazer S2 please

[Dadbob11]

 
My Oxford tank bag doesn't fit correctly because of the 'hump' on the tank resulting in a big gap at the back, so the bag rocks backwards and forwards.

I was considering a HELD Expandable Tank Bag Tour 10-19 Litre Magnet as it's supposedly "...designed to follow the curves of most new sports and touring bikes".

Anyone any experience of this tank bag on a FZ6 or recommendations for a good alternative?

Thanks!
