Drilling and tools
The High Impulse inner core is the engine inside the Enzo and it is perhaps the most unique in the MOTIV product line. With a high RG of 2.57, the High Impulse core spins slowly in the front of the lane, making high friction surfaces and lighter oil patterns less of a concern. However, this core has a substantial diff of .050 that allows for many drilling options, varied strengths, and flare potential. Finally, the High Impulse features a dual density build capable of creating ample shape down lane.
