If the eight cents/mo/share is the motivation....and you wanted something directly related to the Bakken then you might be better off with NTI since the distribution might be significantly better and the growth might also be.....and, if you compare both charts of PBKEF & NTI you will very quickly see a BIG difference.
If i my also suggest CVRR this thing is a mover. I have played it twice and am up over 9% on those plays. i am now happy to hold my 1500 shares now. You don't need alot of stocks to make money. just trade around a core and boom you have the secret.
