The NAP shockwave isn't bad & is better than the spitfires if you ask me. I do like other heads much better than the shockwave. I really like the golden key reapers & demons as well as the rocket steelheads, hammerheads, and wolverine 3p. I have been using the golden key reaper this year with great success and am very happy with their performance.

Dicks Sporting goods did have the golden key reapers on sale for 12.99 for 3 which is a great deal on a great mechanical.
