Try smaller pools.
As long as they can crank out a block every 24 hrs, you'll get your fix.
You'll even make more BTC because your miners aren't dropping all the time.
Smaller pools also give you bigger "chunks" of bitcoins so you pay less to send you bitcoins later down the road.
Variance is a factor with smaller pools, but over a week or more time period it doesn't practically matter.
Stability + Larger Payments = profit
Backburn, that's cheeky and somewhat lacking in truth. The only difference between large and small pools is that at small pools there's more variance. Larger payments come less frequently, so your equation reduces to:
Stability = profit
And stability is the important factor. Once difficulty increases sufficiently, DDOS won't be a problem.
Of course you do. Where else would a pool op mine, if not his own pool? Very cheeky, backburn. Very cheeky.
Btw, thought about telling us exactly what you were doing to your stats before you became PPS? I'm still very keen to know. I want closure. I could sue for mental anguish, you know
