I ran Winmax W6.5 F/R on my z with re71r, they were fantastic, bites hard, works well with little heat, and didn't fade.
Currently I use XP10/8 combo as well, very great pads and they are quieter than winmax.
Now, I am between getting XP12 F/R, MX72 F/R or winmax again. I am looking for better initial bite, and I feel it will be better for trail-braking if I got the same compound for fronts and rears.
