I just bought a 4x4 and it works great on both field points and broadheads. Forget about pulling arrows out with two fingers, though! It gets easier the more shots you've taken, but one of those rubber arrow pullers is a good idea. Also, if you shoot broadheads you should take two or three older ones and disassemble them, then (very carefully) round off the barb (rear point) of each blade on an emery wheel. This will prevent snagging when you pull the arrow out, and increase the life of the target. If you round them off just a little it shouldn't change the weight too significantly.
