Motiv designed the Thrill Pearl balls to offer length as well as control when the lane oil is light and there is a lot of friction. These balls feature the Flux weight block which has a higher RG in order to delay the balls reaction on the lane and generate the length required on lighter oil. The very low differential found in this ball helps to minimize track flare and also assists in ball motion control at the lane's backend. The coverstock used for the Motiv Thrill Pearl is the Agility XP (Striking Precision) and is finished with a 5500 Grit LSP. This ball is great for beginner bowlers as well as seasoned high rev bowlers looking for a good dry lane ball.
