I've looked into brake fluid specs vs price quite a bit.

Based on this, I've been using Gulf RF1000. Dry boiling point is about as high as you'll get, and the wet boiling point is good.
However, because it's such good value you can change it often enough to never worry about the wet boiling point.

However, when you say your brakes are 'going off', what do you mean?

If the pedal is still firm but you're not slowing down then it's the pads that are the issue.
If the pedal is getting spongy and closer to the floor, then you're correct that fluid is your problem.
Ive run that in my Radical for the last two years ( not the same lot i have changed it once) altho i do only track day its never been a problem and will do 25/30 min session without a problem.
