After eliminating strings with unusual words I'm left with:

? ?   ?? ? ???  ? ??  ?? ?   ? ?? ??   unused letters
maverick subdue hinge feller ziti wrap ajopqxy

wavering subdue fiche jolter limy reap aikpqxz

It doesn't get past the first six words (even on the strings that were eliminated).

Trying from the bottom up it doesn't get farther than four words:
