I shoot a 75 grain rocket mini blaster.One and three quater inch cut.If I went to a larger 125 or 100 grain broadhead my arrow would slow down and I would not be shooting 285fps anymore.Heavier doesn't mean more penatration.Goes back to kenetic energy.Speed can make up alot.I have also found that small broadheads fly very well.I guess it goes back to what you like.
