I ordered a new gaming mouse pad on Amazon and it arrived today. It's from Reflex Labs, it is 36" long X 12" wide. It also is the tall mat, which you can choose between heavy or heavy tall. They also come in three sizes of length; 9", 15" or 36".
$19 on Amazon; http://amzn.to/2cjKpJC
I was using a Razer Firefly (https://youtu.be/-hl3GYEz8Fk) previously. I'll still use it but for certain games (BF / CoD) I need a larger pad area.
I like the thickness and mushy feel of the Reflex pad vs. hard surface area from Razer. Plus it will help with my keyboard from sliding when FPS gaming.
I have a short video of it here; https://twitter.com/tyrannicalchris/status/774307343274242048
