I tested these against the Thunder head and Wasp Cam Lok. These G5' s were far and away the best in my tests (which are not as comprehensive as 5-Shots test). They flew extremely well, penetrated the best and are more durable. Hope this helps. [b]They must be popular cause the only two pro shops in my area are out of the 100 and 125 grain models. I' ve got mine. [:-]
