has anyone had any experience with the wal mart spitfires because im am really hurting for broadheads.I only have one good muzzy left and i was thinking of getting a 3 pack just in case i would need a follow up shot. Don't worry my bow is properly tuned so the will maybe i should say should hit in the same place. Do you think they will be alright as a back up just in case? because i dont plan on using them as my primary but as a "just in case"? I have enough KE for them, and i plan on getting some good ones for next year
