RE: Grim Reaper 1 3/4" OR Wasp Jackhammer 1 3/4"?
I've had good luck with both the 1.75" and 1.25" Jak-Hammers. I've had good easy to follow blood trails, and dead deer at the end of EVERY one. That being said, I've heard good things about the reapers also, so either way, as long as you put the arrow where it's supposed to be and have plenty of energy (55ft/#'s for a WT Deer), you should do well!!!
