I'm mining with 2 antminers S9, 2 amd 7950 HD (GPU), 1 R9 290 X3(GPU) and 2 CPU on i7 5th and 7th generation (
You should point the two S9's at Kano pool for one of the best returns for a small-ish pool. Less people to share the reward with!

Just my humble and experienced opinion.

It's been a lucky month on Kano. (But, of course, that's no guarantee of future success.)

Good luck!

The GPU's and CPU's are not welcome on Kano, BTW.
