they'r all shit

What would you recommended, if I like the friction?

sandpaper

Sandpaper

so you are french anon... EXPOSED!

Which grade to have similar feeling like Mantis Control?

:D

I heard that the control version is actually marketed wrong and it offers more speed glide than the "speed" version.

If you like friction, my suggest will be these following surfaces:
QcK+ / Heavy
EverGlide Titan (I've heard people says that it have midrate-large amount of friction)
PureTrak Talent (in the first month its like smooth, but after it friction becomes more balanced)

I heard that mantis is better and it was supplied to razer by everglide, while goliathus is razer's own production. Albeit i can't confirm that mantis is better, as i only tried goliathus myself. Didn't like it, and exchanged it for speed edition.
I didn't like that i can feel texture while moving mouse and it was very harsh for the wrist. Although it's really a matter of preference/getting used.

I can confirm mantis speed is everglide titan as I ahve both and they are more or less identical
