Pros: easy to get used to
Cons: not wooded bars like you may find at some competitions
These bars worked for me when I was doing class one (current level 10) and collegiate gymnastics. I found a grip was hard to get sometimes, but I believe that is because I didn't have a good chalk ritual/preparation and I am not very good with grip in general. All my teammates who are good on PB like them and some of them compete internationally.
