Camofire had the TKO on sale in the .003, and .006. Thought I'd buy a dozen just to try.
Shooting the 400's out of my Habu Death Adder longbow.
When you find a shaft that bare shafts perfectly, you stick with it. I draw 28", and cut them to 29.25"...bullet holes.
I like 200 up front, so I ordered the 50 gr outserts, and shoot 150 gr Centaur broadheads. The aluminum outserts will bend on hard impact...I suggest getting the stainless steel (although they weigh more) from Valkyrie archery.
You can really customize the hunting weight of these arrows...a pain for some who don't like all the accessories...
So far, I really like them...can't comment about hunting since the two deer I shot at this year, both jumped the string.
