Congrats on your first! It becomes addicting!
I gave the grim reapers a try this year after hearing all of the reviews on here and I will probably keep a couple in my quiver from now on. I still like the idea of fixed blades but I am impressed with their performance. I shot a mule buck a little high and back, buck fever got the best of me but I got both lungs and a little bit of the liver. After his first three steps I knew I had a dead buck, I seen him start to fall as he crested the hill. But same thing I couldn't find much blood for the first 80 yards. I think it just took a few seconds for his chest cavity to fill before it started to trail heavy. I think the blood trails are there but are just really hard to find without snow!
