to add to the advice from pendlay on that link nine posted:
I train on all Eleiko training bars at my gym. We have 8 of them, plus 4 eleiko womans training bars, 3 elieko mens comp bars and 1 womens comp bar. We have one bar that has a sleeve that sticks if it spins in the one directon to far. Its marked and used to squats and pulls only.
We also have a prototype IronGrip bar, but since you cannot buy it I won't comment on it.
I had a meet @ LBH and I warmed up on a York Comp bar, and another bar I don't know what it was. The york bar felt a bit thicker, and I did one set of warmup jerks on it and went to a different bar. Not enough whip imo and the other one was very nice. I think it was an elieko but I'm not sure. Not saying the York bar is bad, I liked it for snatching and it felt very good. I would buy it for my home gym when I finish it.
I have friends at another club down south with a Werksan comp bar they train with. They say its the best bar they've used yet and they are now spoiled.
imo, york is a good bar, but if you can afford it, grab an eleike or werksan.
