Ball type recommendation question:

I bowl in a late league which starts after another league. For the first game or game in a half, I am fine to use Black Widow 3.0. I throw a bit more speed dominant and am definitely a 10 board up and in person (10 dumper or whatever Kyle calls it 🙃)

I have tried going to a strong/sharp ball (Equinox Pearl) for the 3rd game but I just end up leaving some ugly splits. 

What is the appropriate ball change for a situation like this? I was thinking of getting a weaker ball (the OG Phaze II) but it's more recommended on fresh patterns. Should I go to just a weaker pearl ball? The solution might be to open up and play more angular instead of ball changing too. Open to suggestiosn. Thanks!
