Sorry for spamming but another zip file test:

orig zip size: 31.4mb

zlib: 31.4mb
reflate: 85.9mb
preflate: 49.5mb
grittibanzli: 101mb

then srep+xlzma:

reflate: 26.3mb
preflate: 29.8mb
  grittibanzli: 25.4mb

3.4% better final compression of grittibanzli vs reflate. Preflate look weak so far in every test for me. Looks like zlib+reflate and/or grittibanzli are 2 best general options.

EDIT:tried on another 2g file, grittibanzli took a freaking 20(!) minutes and loaded all cpu cores to max nonstop, pzlib+deflate took ~2min with much smaller cpu activity. Final compression was around 860mb vs 844mb only. That leave pzlib+deflate the only and best viable method for me.
