Can't comment on CPL, but suggest you look at KMR (for IRA accounts) and KMP for taxable accounts. These sister companies are oil & gas pipelines that transport petroleum products and are less sensitive to crude price swings. Currently paying about 8% dividend, which has increased each year for more than 15 years. Company is managed by award-winning CEO Richard Kinder, who takes just $1 a year in salary and lives off his KM* dividends --- so, he puts his money where his mouth is.
For pure growth, look at DVN or DO, oil drilling companies that will experience large capital gains as oil prices rise during the next 10 - 20 years.
