Mousepad

Who uses what for games? I play shooters. Generally without a rug on a regular table. Now it's hot - the hand sweats, sticks to the table. Terribly awkward to aim. I'm thinking of buying a rug. Will help? I understand you need a carpet of decent size? Who prefers what material? I looked after the A4 X7 Pad X7-300MP. Like big (437×350), fabric. Who is like this? How are the impressions?
