Thought I would share this experience. I've been away from Kano for about four weeks, but it was by design.
Back when I thought the US govt was going to shut down (I had a very bad experience resulting from an earlier one), I emptied my Core for cash so I could pay my rent if my VA disability or SSA got bolloxed. But then, I had to pay my quarterly hosting charges...in BTC...soon. We were not doing all that well here at Kano at the time.
The solution (for me, at that point in time) was to move to Slush for only enough time to get that quarterly billing back in BTC reserve, which I did.
I'm back at Kano now, Whilst I was commiserating with Alan on the Ice Planet to get the assignments changed, he pointed out (chuckling at the time, methinks) the foibles of pool hopping...but then acknowledging that sometimes the situation demands what some would call an odd tactic. In this case, at least, it worked...for me.
I also ran numbers for the past month re both pools just to make myself feel better that it was indeed the correct choice to return...and if I had been at Kano for those four weeks, I would have earned .096 BTC...but it would have come too late to pay my obligation. I earned .077 at Slush for the same period. The result was what I expected, but nonetheless made me feel better.
So...this is the best place to be, IMHO. Always has been. When I left solo mining years ago for Slush, that was about the only choice I had. Kano started his pool, and I went with it.
As we say in Team Rubicon...you cross your personal river Rubicon...and then you burn the boat.
Mine on.
