I am a little surprised that unit does not have a chirp compatible sonar module for that price point. Their 50/200khz processing is very impressive so the B60 should cover all the bases. The 260 transom mount is a beast and before I would hang that off the back I would go with a tilted 264n pair. Lots of $$$$ in the last two options. I would go with the b60 and spend my money later on what's coming down the road.
