I swear by these as well.
You can be rough as hell when you're cueing and that sh*t is not going anywhere. With those cones the 45 would still slip underneath sometimes and it would drive me crazy. No longer a problem. "Mat's Mats" aren't made anymore but you can make something close enough yourself with some regular slipmats, the plastic cone adapters, and some heavy duty bonding glue.
