I switched to Kudupoint 100's this year. I was a little concerned about blood trails prior to using them, but I've been pretty impressed so far. I recently ordered the contour+ kudus with the bleeders, but haven't tried them yet. I've shot Montecs since 2008 and the blood trails were never great, but I don't think I've ever had a deer fall out of sight. I wanted to switch due to durability. The tips would consistently chip or bend on them after hitting the ground on pass throughs.
First kill was a pronghorn (20 yards quartering to and downhill). I hit him in the chest close to the shoulder joint and it sliced his belly wide open on the exit and his entire stomach dropped out. The arrow buried itself in the grassy hillside and I never recovered it. There wasn't a ton of blood, but I watched him run about 80 yards and bed so I didn't look too much.
Second kill was a whitetail doe (45 yards uphill quartering away slightly). The arrow passed through the front shoulder blade and exited just in front of the off-side shoulder and stuck into the ground in rocky soil. The deer went about 40 yards and the blood trail was pretty massive. (I do think the quartering angle helped open the exit would wider as it was pretty massive.) Recovered the arrow and the broadhead still looked new. I put it back in my quiver to use again. One odd thing to note, I had a lot more meat loss on this deer from the wound channel than I can recall on any other I've killed with the bow. I would've thought it was shot with a rifle.
