Well, coin control is indeed working nicely (when I keep the total amount of bytes below 100.000) and I am in currently the process of moving all around (bitchjob, but if I can stake for my full amount well worth it) ...  any reason for that 100Kb border by the way?

(This does explain some other issues I had with other coins I mined for a longer period; with Myriad for example I could not send more then ~ 100K , so I guess it's common behaviour)

For anyone else who is moving coins by coin control:  the sweet spot seems to be 675 inputs
