La Bella makes a set specifically for D-G-C-F tuning. The gauges are 54-75-90-111. I play in D-G-C-F tuning about 75% of the time and I highly recommend these strings for that application!
This is where I get mine (the page has the gauges listed wrong, but when I order them the correct strings show up.) http://www.juststrings.com/lab-m70.html
