It's up to you to NOT let ATC fly your airplane for you. As far as I'm concerned those spoilers are for landing. Any other use is poor planning.

Planning is fine but it seems that with 55% N1 for engine anti-icing, you need full flight speedbrakes just to get 1,000 fpm descent. The ol' 72 allowed full speedbrakes in flight. And if you were 20 back on the glide at 250 with no speedbrake, you just configured while descending on the glide.
The 73 seems a little wobbly on occasion in ground rollout as well, possibly due to shimmy dampers on the main gear. Maybe just a little Tonka Toy-ish.
Must say that the autopilot is quite a nice design.
