Al,
The Tuffheads are wonderful broadheads, and Joe Furlong, the developer, is a gem of a man. Being the same basic design, I am sure the lighter Meatheads will perform similarly. I used the 300 grain Tuffheads with a 100 grain adapter in Australia. I also had a 100 grain brass insert and an aluminum footing at the pointy end and unibushings with G-nocks at the other end of my AD Hammerhead Trad shafts. I used 4x4" fletching on the 1000 grain arrows that were shot from my 60" 70#@29.5" Shrew Safari takedown longbow. It was a great combination except for one thing. The steel broadhead adapters were made from relatively soft steel and had a tendency to bend on impact, even when using them with the 300 grain brass glue-on field points that I got from Tuffhead to match the weight of my broadheads. I'm not sure where to get high quality broadhead adapters, but that was the only weak link in the equipment I took. I used an EFA Mesa quiver with the Totem and the Wing accessories. The Mesa held 4 arrows with broadheads and a fifth arrow with a hex head blunt. The Mesa was long enough to cover all but a little of the Tuffheads. The penetration with the Tuffheads on Asiatic Buffalo and Scrub Bulls was as good as or better than anything I have used. I also like the 2 blade VPA broadheads, both the double and single bevel versions, at 300 and 325 grains, respectively.
I have been to Africa to hunt 6 times now, and it is the greatest hunting destination in the world. You are undoubtedly aware that Cape Buffalo are in a different league from the Asiatic Buffalo there in your native Australia as far as aggressiveness and danger, although both are similar in their physical structure. Africa has a very rich diversity of wild game, so there is always something else exciting to hunt! And the weather in their winter months (summer in North America) is very pleasant for hunting. I have always wished I could spend a month there hunting every year during the May through August period.
I had the same experience with Grizzly Stik shafts as you did. I really like the guys at ABS who have done great things for bowhunting, but I greatly prefer the AD shafts in all the Trad models. I shoot almost exclusively AD shafts and have nothing but great things to say about them! I do have my preferences about how they are set up as completed arrows, depending on how I plan to use them and how tough they need to be for the intended purposes.
