TerryM--the Slick Tricks heads have impressed me a whole lot.
I've taken moose at 38 yards and at 42 yards, using a 55# bow equiped with a 27" -373 grain arrow (100 G STEELHEADS).
I can assure you--if the Steelheads can do it--the Slick Tricks will.
This last season I filled two tags with the Slick tricks and they made an impressive exit wound on both animals--so much so, I stuffed the wounds with 'snow' to stop it from bleeding--so I don't leave a blood trail thru the farmer's snowmobile trail.[8D]
