Cambridge Springs vs. Botvinnik in the Semi-Slav as Black

I started changing to a Semi-Slav repertoire againat d4 a year ago, and followed Shankland's Chessable recommendations with playing ...Nbd7 after 5.Bg5 and going for a Cambridge Springs setup.

However, I often get very unpleasant positions, especially when White decides to sac one or even two pawns for a massive lead in development and a big space advantage.

(Shankland calls these positions something along the lines of "probably fine for Black")

I recently started studying the Botvinnik (...dxc4) as an alternative and while extremely double-edged, the lines are very concrete and relatively easy to remember.

How has everyone else fared in these lines? Any other factors to take into account? I haven't tried the Botvinnik in Classical yet so my opinion might change.

My rating is around 1850 FIDE by the way.
