We have 90% of our farm pointed at Kano, about 1 PHs (1,000THs). That's 78 machines right now. Variance is high on a pool this size but we have been very happy with the results thus far. It's nice being in a pool where the administrator is so engaged and the payout process is so transparent. I would recommend you go all in but plan to stay about 3-4 months for the variance to even out.
