I've seen a few people throw it...one of which replaced an original Puma with it. Ball looks really good to me and it's a bit stronger than the original.
The only thing "old school" about the product is the core shape. Light Bulbs are a great classic shape that still performs well on today's conditions. One of my favorite all time balls is a Storm Lightning Flash that has an inverted light bulb. Now that ball is a little more "old school" as the cover stock is weaker by todays standards, but the ball works well with my rev-rate.
Give it a try...but make sure you are looking to use / drill it for its intended conditions.
