Now that the fees on slush have been dropped AND merged mining NMC introduced, I am as sure as can be that payouts at slush will confortably exceed whatever kano.is can expect to payout, even with the supposed better luck that you claim for kano.is;
So, that being the case, why don't you do what johnnybravo has done elsewhere, and point some hardware at both, record the payouts, and compare them so you can prove your point, rather than continue the cat fight back and forth.
Really, I could give a shit less about what you, or anyone for that matter, "think" or "know" about any pool being better than any other pool with regards to luck or payouts without empirical data, and I'm sure most of the rest would agree. And, this does not except Kano from that statement either, but he at least has proven before to provide numbers and calculations to attempt to support his assertions, instead of specious knowledge and feelings.
If you prove it with numbers, there is no ability to question or deny at that point. Until then, it's merely speculation and attempts to denigrate.
