Bbks are the best grind plates ever. They are thick so you can grind on plenty of curbs and ledges, then when you wear them down you can shape grooves in them for handrails. You can do the same with the express plate, bbks are bigger than the express though. Some complained that they made shoes heavy, I didnt see the big deal though. Unless I'm wearing a pair of express, I don't notice the weight of the shoes that can remove the grind plates

only plates ive ever used are express lol =/
