what do you use for Mining dutch for multiport for Difficulty?

always wants to mine the most profitable coin, wanted to try it out to see if it really works better than going straight to a coin
dont have much luck with mining dutch with X10. anyone else using it?
Me... in Mining-dutch you have to stay for long, to see real profit, currently, the best option is myr-gr; I have set the diff at 21; d=21, best results for me, about 12 to 16 per day
