Should I buy a stitched-edge mousepad instead of a heat-cut one?

Yes, stitched-edge mousepads keep their glide uniform much longer because the stitching holds the weave together as the center fibers wear down. Heat-cut edges can fray or develop a lip over time, making the glide feel inconsistent near the edges. If you care about consistent aim and muscle memory, spend the extra five bucks on a stitched pad.
