I have a Backlash Blue/Silver drilled 5" pin to PAP, pin under bridge. 4000 abralon. I'm getting a Tropical Heat Black/Silver from a friend. Drilled 4" pin to PAP, pin under bridge. 1500 polished. How would these two compare? I'm thinking the Backlash will be smoother while the TH will be a little more angular on the backend. Which ball do you think will handle more volume? Thanks.
