My dad has a Parker Terminator HP that he bought last year. The Parker arrows do have brass inserts. He is shooting a 125g Spitfire. It is accurate and consistent. 125g heads are probably over killand I am sure that the 100g heads would shoot just as well and there is a wider selection of broadheads at that weight. FWIW the Parker arrows come fletched withstraight fletching on them. I re-fletched his arrows with 2" Bhoning Blazers with a 4 degree right offset and the groups did tighten up some.
