Question about baseband versions.

I am still running a KitKat ROM and I recently returned my phone to stock because I was about to trade with someone. That fell through so I rooted and installed an NI2 kitkat ROM again. Service at my house seems a little worse and I'm thinking I may have flashed a different baseband before.

Currently on NI2 and wondering what other baseband I can flash while on KitKat?
