magura mineral oil will do fine...although as that is pricy; you can use citroen clutch fluid ( exactloy the same stuff, although im not too sure how easy the latter would be to buy out where you are ).
I personally say: Rear magura or front bb7 Front vee is sometimes better if you're not particular bothered about modulation. But for me this just isnt an option; as i have to ride 4 miles to the station every week...and a lot's downhill. kind of interesting when your front brake decided that it wants to bite and hold instead of slow you down.
