Hello dear fellow miners!

I have been small home GPU-miner since the beginning of the year, and have spend hundreds and hundreds of hours on research. Unfortunately I dont really have anyone to spar with. I am hoping some of the pros here on bitcointalk might help point me in the right direction.

The situation:
I recently recieved a 80k USD investment to expand my small home mining farm operation. While i might use some of the cash on investment in cryptos the majority is expected to go into mining. Please keep this in mind before you type BUY BTC. 

I have a cheap (300 usd/month) facility with up 300 amps at 220v. I pay around 0.055 usd/kwh).

I am almost done setting up the place with airflow, security, network and the works.

Initially I was planning on a 50/50 GPU/ASIC split, but as the marked looks a full ASIC focus seems the obvious choice to me.

The problem:

What to buy?
I am thinking I will start off with:

2 x Antminer Z9
1 x Innosilicon A9 (would focus more on these if it wasn't for all the bad things i read about Innosilicon)
1 x Pangolin Whatsminer DCR (november is a long time away though)
5 x Whatsminer M 10.

Which is about 25k USD give or take.

Then hold on to the remainder of the cash for a few months, waiting for new hardware to surface. The Avalon A9 seems as a good option, depending on pricing.

What do you guys think? Any feedback is much appreciated !
