Probably come a time where you will have to have bumber plates. Even with those you will still probably need floor protection too, depending on your floor.
I've done powercleans, high pulls, and things like that and I do high pulls a lot now. Generally I haven't seen any need to have to drop the weight. And since it is very light compared to deads so I can put it down safely. I'm not training to become super strong at those but for right now I suspect you may have failed to keep your shoulders back and "locked" while you were unwinding the weight. Course you may be a beast and clean a bunch more than me
. Regardless, no, bumber plates will prob be a necessity. I know they are expensive as shit. You don't have to get them all at once as you can intersperce with with smaller metal plates but depending on how much you lift you will need enough disperse the weight. Regardless, you're looking at mucho bucks. It's not as bad as dropping the bar from overhead but you also need to wonder how well your bar can hold up..even with the bumber plates.
