Hi,
now I'm using all of my coins only for mining.
Today I solved 9 blocks. I'm using 1436 version on my VPS and 1437b on WIN. Yes, it is laggy, but it works. It looks that I need around 2 hours to reach 256k weight again, I hit the block, It spends all of my coins for ABN and then it goes round and round again. I have not used  exec bankroll, but maybe I ll try it. But definitelly it looks, that it is not neccessary, because when you mine all the time, I always hit the block right after all of my coins have coinage 256k and they are spended all.
