plastic for me
tried alu and glass, worst experience ever, cant say it was bad because of material but it makes noise heavily loud
crispy sound
cloth, the only one that i found it could worth it, was actually cloth pad from Artisan, best cloth pad i ever tried, friction rate was very low
the biggest advantage to hard pad its the non-friction rate or way lower than cloth
you must try both to notice it
i currently own Razer Destructor 2, kinda love it, almost perfect to me although i think its surface provide very fast glide and you can feel something that sticks mice's move a bit: in the other word, i would call it grip but you actually feel like tiny grains of sand when you move your mice
