Review
This is an excellent kit. Of course, you have to use it with a barrel that takes Freak inserts. Given that, it is hard to beat. On most barrels there are only three backs. Granted, that covers the majority of paints, but only about 75% for me. I usually end up wanting a different size than the typical three and this kit fits the bill. I also like the 0.679 for those rare occasions where I had to use tiny paint. Highly recommended.
