My mistake, I only checked the first link. Those were high bar dowel grips, which can seize up on you when you're either either clenching the bar too tightly, or going very fast with a grip that doesn't fit you right. If you're on a high bar, that'll leave you with broken wrists. On an Olympic bar, it'd just yank you forward into it as you dumped, I figure. I've never actually seen or experienced this (thankfully), but I was warned very strongly to not use my ring grips on high bar, since they are made differently, and would increase the odds of having that problem. The second link would be okay... But I'd go with Steve's suggestion first.
Also, I'm fully aware that lifting straps are an entirely different thing.
