Pros:Consistent size, Easy to work, Very smooth surface, Box oval shape, Great release
Best Uses:Easier than slugs, Cleaner release
Bottom Line:Yes, I would recommend this to a friend
The box oval shape works great for a clean release. The material is easy to work but also takes a very smooth finish. Compared to plain oval inserts, very little material needs to be removed to fit the bowler. Compared to round inserts very little tape is ever needed; great product that everyone should try. The sizes are quite consistent from one lot to the next.
