I have shot deer with Thunderheads, MUZZY's and now Shockwaves. The only reason I switched from MUZZY's to shockwaves was for arrow flight.
As far as blood trails go, I think alot of it stems from #1 shot placement and #2 how spooked the deer was at the shot. I have had numbers of deer run for 50 yards and pile up hardly leaving any blood until the last few yards of the "ending". Simply they run so fast the blood dont have a chance to leak fast enough even with full pass through of the arrow. On the other side with a wind of any amount that can cover the sound of the bow, I have had deer take an arrow and not hardly flinch. Lots of blood and walk 20 yards and do the big "rear end falling out" circle and fall over. Never knew what happened.
To answer the question, I think there is too many variables. Get a good broadhead that flys true, make the shot count and everything will fall together. A 1" vs 1 1/8" broadhead personally I think is a mute subject. Put it where it needs to be and you will find blood, just maybe not right away or possibly instantly. If you see the arrow coated with blood on the other side of the deer at the shot, chances are, you will find a decent blood trail.
