Which leaf springs to use?

Not the piss poor metallurgy several runs of the SS springs got. I've seen some less than a year old that were bent backwards at the front spring eye bolts. They flat out suck. I'll go for something from ESPO or General Spring now.
Got any links? How many have you seen bent at the spring eye? Ive never had a problem with them, so I’m goin to keep running them and recommending them.
