Which would it be easier to change, the entire legislature or a single senator? The 49% of Republicans, for example, in a majority Democratic district basically have their voice taken away. Their legislators will put a Democrat in regardless of their wishes. But if Senators are elected then they have a better chance of their vote counting when combined with Republicans from across the state.
That is the crux of the problem, isn't it?
On the one hand, removing a single Senator may be easier, but how many one-term Senators have there been who weren't removed by scandal? On the other hand, changing the legislature would me more beneficial long-term.
That said, one would have more opportunities to change the legislature (2-year and 4-year offices) during a single Senator's term of office (6 years).

Correct point.
The Senator might be selected as a result not of the majority support, but do to gerrymandering that helps a party.
