I bought the original version of this with the stitching that comes loose and the smaller arm holes. Neither of these issues have been a big issue to me, but I would like the larger arm holes in the new version, as the old ones were quite tight. Overall, I really like using this piece of equipment. I normally do max bench beforehand, then use the ballista to add some extra weight. I bench around 175kg raw, and with the ballista I'm getting 185kg-195kg. The spring off the bottom assists the rep without being too powerful, but it helps to break through the sticking point. Also, be sure to bench in a rack or with good spotters, as when a rep goes wrong it can go bad quite quickly.
