We just use the chest protector/skid-plate variety and they work great. The underside seems to be what gets scratched up the most.
Forearms too, but we opt for maintenance rather than donning her with too much gear. Getting a couple scratches is part of it.
Forgot to add that I think we just got a basic chest protector from gundogsupply. You can find more expensive/heavy duty models I'm sure. It also seems vest sizing is difficult for pointers because they can be so barrel chested, so you may have to do a bit more trial and error there if you opt for full vests.
