B2B kits are designed for the first time builders. They include the classic shapes that I grew up on in the past. These kits, are a little more blocky, a little more wood. A little more sanding as these bodies will primarily be cut with scroll saw instead of cnc routers to help reduce the costs. They are not going to be perfect. Expect some dings. Expect your Tiger, and Bobcat to do some sanding.
