i got the scorpions last year because they look basically similar to a spit fire with a razor tip. ive killed a few with the spitfires but i did loose out on a monster of a buck last year with the scorpions i feel do to a quartering away shot that went wrong either placement or the broadhead not doing its thing on an angle shot. 2 days of tracking and i couldnt figure it out so im trying the grim reapers this year because the main blades are set back a little further than the scorpions or spitfires. this is supposed to help with not throwing off the blades by only one hitting first and making the arrow do funky stuff. usually i will try not to make any fancy angle shots but with expandables i would rather have perfect broadside from my experience.
