Best recommendations for brand? Changing to Dot 5.1 fluid

I used Castrol React Performance dot-4. it's good stuff.

I heard ate racing blue is very good

I just use halfords advanced dot 5.1

I have whatever mountune put in mine lol

i went with Halfords, easiest to find by tomoro

hi everyone.

is ATE TYP 200 fluid ok for ST?
I don't get the difference between TYP 200 and Super Blue except that super is more expensive?

BTW what is this ATE SL.6 which has viscosity different? I presume this is not suitable for ST?
I don't get it, if it's different fluid why the hell are they calling it DOT4?

cheers.
