should I send my act or sat scores?

some of the schools I want to apply to require either act with writing or sat with two subject tests.
for act composite, i got a 35, but only a 21 on writing.
for sat, i got a 1540, and took three subject tests. i got a 790 in math ii, 700 in lit, and 660 in german. will schools see my horrendous german score if they only require 2 tests?
so, should i send my good act with bad writing or good sat with meh subject test scores?
