Have to agree with what has been said above especially with the 1/2 mile track. If you double lung a deer with a field point it wont go a 1/2 mile.
Been piling up venison, pork and bear with WW's since before thay were publicly available and as long as I do my job they have never let me down.
For the record I have never done anything to the tips until they have shot or missed a few critters and needed tuning up. Personally I like the needle point but everyone has an opinion about it.
I have killed deer with about every COC type head out there and if I only had one shot that had to count there would be a Woodsman on the business wnd of my arrow for any game animal.
All that said, I think "equipment confidence" is paramount to hunting success. If you think your bow, arrows, glove/tab, heads wont get the job done while sitting in the woods you are cutting your odds in half at least. Go with the heads that bring you confidence - there are dozens to choose from. If you don't want them anymore and want to improve your broadhead karma I will happily take them off your hands?
