Not spooking him was a good thing, How close to his trail are you I know you said you saw him at 85 yards but is that also where he went in ? if SoI would move no close than 25-30 yards provided the wind is good and also most importantly the cover !!
as far as calling Me personally I go with the antlers first and just tickle them Not smash I have twice in my life called in a deer with a call, so I go with the antlers first and if posible use real ones. IMO it does make a differance. not to mention thats what works best for me Where I hunt.
Good Luck
