Flatback at the front (some vendors call it pompador) and freestyle the rest is what I prefer on my full caps.

The advantage of freestyle is that if it starts to thin out too much in on area you can easily change the way you comb the hair to hide the affected area. I find that if I comb it to the right for a couple of months I invariably get shedding along the break line. Combing it to the left covers this up and extends the life of the unit for a few more weeks.
