Well put, and just to expand a little: the combo of stiffer flex + shorter EE makes for more horsepower and tighter handling like a sports car. Amazing for the right pilot, but they need to be piloted for sure.
The BC120 is more of a "performance SUV" kind of thing. Big sweet spot and really well rounded. Fast and fun, but more versatile/forgiving in marginal conditions (going too fast over speed bumps, to continue the car analogy).
