As with anything you need to do your DD. Right now DUNR is about to explode--check the details. DUNR is going to complete a HUGE well in the next month or two that will be a game changer. MNLU is dead money for a number of months. I like what MNLU has to offer down the road, but huge money is to be made in the next few months with DUNR. Make some $$$ with DUNR then put your profits in MNLU in a couple of months. MNLU might even be lower than it is in a few months.
Advice is cheap. Once again do your homework.
Good reads on both boards are to be found---especially by "geopressure".
