I've got to buy myself an olympic barbell set, because I've just found out the bar I loaded up to 500 lbs last night is only rated for 330!! At least I can justify it to my wife on safety grounds, I mean "do you want me to die?".
I've found a couple of sets (only Â£10 price difference) one smooth sided the other "tri-grip".
Was going to go for the flat sided, mainly because they look better. Is there any advantage to having grip holes that I'm missing?
