36. Cores Designed to Affect- 1)Flare (Differential Rg) and 2)Roll (Rg) Core Body- affects Rg, high density material, 2.0- 3.2 Sp. Gr. Bottom Flip Block- affects Diff Rg, very dense, 2.0 to 3.5 Sp. Gr. Top Flip Block- affects Diff Rg, very dense, 2.0 to 3.5 Sp. Gr. Round Core- affects Rg, lower density, .7 to 1.2 Sp. Gr

40. Other Future Ideas

41. TEC Death Issue

42. TEC Death Issue-Capture

43. Hook Again vs. Capture

44. Effect from Color

45. ABC Strike Percentage Graph Idea strike location 10 Pin Location- approx. 50% strikes & 50%-10 pin Believe deflection determines whether the ball strikes or leaves a 10 pin
