I would go with this one from Rep....https://www.amazon.com/Rep-Sabre-Olympic-Bar-Barbell/dp/B0170DYOOM/ref=sr_1_27?s=sporting-goods&ie=UTF8&qid=1525804312&sr=1-27&keywords=rep+fitness

Or from XMark, this bar...(I love my two Xmark bars)....https://www.amazon.com/XMark-Commercial-Olympic-Capacity-Manganese/dp/B01I46FG46/ref=sr_1_8?s=sporting-goods&ie=UTF8&qid=1525804355&sr=1-8&keywords=xmark

These bars have pretty decent reviews on Amazon. I’ve been eyeballing some of these for my home gym.

I’m about to pull the trigger on the Ohio power bar stainless steel. Pricey, but I want it.

i think cap boss power bar is the best buy economy option. I have one. Knurl is very passive.

my gym has Xmark voodoo and I love it. Saw it on amazon as well. Decent knurl and no center knurl so it’s my go to DL bar.
