A lot of people swear by those foam rollers, but, I don't like them. They hold very little paint and tend to skid leaving skid marks in your finish.
Personally, I would use a 4" Whizz roller to roll on the paint and then back brush it. Just rolling it on will leave a bit of roller stipple, which, to me isn't a bad look, but, many people don't like that look.
