Since we are talking about more pricey mechanicals I would say either rage two blade or Bloodrunner 2 blade. Either one leaves massive blood trails! i've had a few deer not even flinch when they were hit... they knew the score so they just laid down! They first doe I shot with a blood runner i pulled its heart out in two pieces. With blood runner be careful it you open your hand on your riser though. I ran one down the length of my finger once.... OUCH!
