I was bowling on the Chameleon last night and started with my Resurgence playing around 23 at the arrows to about 8. Then as that shot slowly went away I switched to my Rival and played 20 to 8. However, when the shot really started to break down, I tried my Spit Fire which ended up being almost as strong as the Rival so I went to my Neptune. I was playing 15 to 8 with it, however, it just didn't have quite the pop to carry real well and didn't have any recovery from the outside. So I see that I have a big gap in between the Neptune and Spit Fire. I was thinking of just sanding the Neptune to 4000 or should I look at getting another ball.
