Would the pool be open to having a silly amount of hash rate added to it, or is it kind of in a sweet spot right now where say 50-70PH would hurt the pools share to solve ratio?
Kano has posted a couple of times about his ideal pool size at 10% of the network and we are not anywhere near it yet. Being at 10% would minimize the impact of those monster blocks that visit every pool from time to time. If you could pull off that kind of expansion by all means go for it.
