If you think youre going to reach the limits of Super Blue, then try the Motul if you think your needs warrant your spending more on the Motul. I'm not sure about which brand absorbs more moisture; but if youre using this stuff for tracking, then it's a moot point because you should be changing your brake fluid ecery time you track, and your fluid isn't going to absorb moisture in one day unless you have a leak in system and the track is in the tropics--in which case, the absorbtion is the least of your worries if your fluid is leaking :-p
