FGP---not something I'd want to be holding. The past year has been unkind to it. Don't have time to figure out why but just earnings alone tells me a lot.
NS was brutalized. I wouldn't be holding that one either---far too much cloudiness in an otherwise blue sky.
I like USAC, owned it a year or two back but found greater promise elsewhere.
Your ETP and EPD positions strike me as somewhat anemic. I added a little to each over the past couple of weeks and happily so.
