Was planning to get some 20kg plates soon since my deads are going up pretty fast. But i'm not too sure if its worth paying so much more for rubberised.
you would do better for a time just using metal ones, after all they are METAL! hehe. i dont think you will break them. ask bfold, he broke the bar first before the plates, i think the bar is a better deal to replace vs. buying rubberized plates IMO.
