Seeking paddle recommendations

Ive been self spanking on requests from my various dmdoms for a while now, and ive been using the back of a plastic hairbrush to do it. It stings nicely and leaves lovely bruising if i go hard enough, issue is that it probably cant take much more without breaking and it takes a lot of effort and angling to get it to hit hard enough to cause bruising. So, im seeking recommendations for paddles that are ergonomic enough for self spanking and thuddy enough to give me a nice bruised butt for a few days!
