Hi everyone,
I currently have 5x 1080TI cards mining on NiceHash, but the pay its pathetic atm.
To get setup mining HSR, is it best to use Justaminer's fork or Excavator?

I'm new to mining and am struggling to get the bat file setup properly. It currently reads:
hsrminer_neoscrypt_fork_hp -a hsr -o stratum+tcp://hsr1.91pool.com:9009 -u HJdQzYzdC8FJvr42PLpnNLM1ydnaDMu8fX -p c=GBX

Is this pool ok? It says to use both:
Node1 : hsr1.91pool.com:9009
Node2 : hsr2.91pool.com:9010
How would I set this up?

Also do I need '-p' if I don't have a password?
And what does c=GBX mean?

Currenly it fails to mine with the following message 
Share rejected, low difficulty...

Any help is greatly appreciated!
