FYI If you don't have enough shares to generate dividends to cover market price. Your drip is killed I would say.. I don't want to purcahase at thie price in volumne . This can depend on the individuals protforlio or other reasons. I am long Trp Ipl and some other relalted companiues so it would not be prudent to push the % up. If for whatever reason IPL went south I would likely load up more.. as Buffet says where do you see the company in 10 years!!!! Oil sand should be pushing ahead stronly by then.
