I have to agree with the above post. Due to my recent heart surgery, I had to buy one, and I looked at a lot of them, and got a Parker Thunder Hawk, due to its light weight and simplicity. To tell you the truth I shot long range rifle for a long time, both on my job and competition, so I also like the trigger on it. Anyway, shot a lot of various heads, but I like the Magnus Buzz Cut which is 125 grain, and with the bolt etc, I had more than enough weight, as recommended by the manufacturer. I killed a wild boar with it, in March, at 23 yards, that bolt went thru it so fast, it was crazy....... I think that would fly well out of your cross bow.......
