I've been using a glorious XXL pad. I'm really liking it as it covers a large area on my desk. It does really well for both my log g502 and roccat nyth. Surface tuning for both mouse was needed to get the smoothest feel.
What are you using for a keyboard there? I've been thinking about getting something like that
It is the ergo dox. I love it, and the nyth compliments it nicely. So many buttons added to the thumb area. It was fun building it as well.
That "natural curve" you [roads] are talking about was me taking a wild guess what the game was doing (which was completely wrong of course).
