Dave: I just got back from Africa in August. I used the Kodiak head, worked very well. Shot some very large animals and had complete penetration on all of them shooting a 56# Recurve. I mounted them on a 125gr. BHA, for a total point weight of 325gr. 100gr. brass inserts for a up front weight of 425 gr., shafts weighed around 680gr. or about 12gr. per lb. of bow weight. FOC of over 30, I was very pleased with this combination.
Now, dont even think of using them with anything less than KME sharp. Your PH and trackers will thank you alot. RW
