Question for the people pointing rentals at this pool-
who are you renting from?
With all the scams these days, I wouldn't trust a rental company without some good recommendations.
I give a 2nd vote to MRR - Mining Rigs Rentals.
I haven't tried NH; however, MRR all but about guarantees the hashrate you rent (when rental is done, if the overall average rate is significantly under target, they refund you the difference).
