Drilling and tools
The Cruiser Core is a very long, smoother option which is viable for those looking for more control on the backend. The higher RG and lower differential provides a shape that retains axis rotation without over-reacting as it exits the end of the pattern. This core is perfect for those looking to conquer even the most hooking conditions.
