How do you guys prevent your top from getting ugly marks from your dry wall on it when it falls and slams into the wall :o ???
It’s called aging of the top 
There isn’t much you can do to prevent it except become better Give it time. Which top are you using ?
I notice if I don’t use them they stay new J.K. they always find something to hit on a miss I like soft grass to practice on but in Minnesota that’s only 7 months then look out I am inside I have a piece of used carpet in my basement and a carpeted area upstairs the rest is hardwood floors so I try to keep my practice to the safest area ;but they still find something to hit at times. good luck
Ahh i see. Im using a bearing king with a rusty bearing (it will be fine)
