ORIGINAL: 5 shot
most quality broadheads will shoot fine with a properly tuned bow and the correct fletching. With an untuned bow and the wrong fletching you will need a mechanical head to for the most part to get the same impact point as your field points. There are a few fixed that will do it as well. Slick tricks, sonics, turbo's etc. I think you really need to make sure your bow is tuned, first then figure out what broadhead you really want to shoot. Here is a link to help you get started tuning.
