I've had lots of luck with scent drags. No giant bucks, but several decent 2.5 year olds, which is just about all I ever see in my area.
The more precautions I take to prevent human scent on the drag or the rope, the better the results have been.
I'd say start it on the trail they're using, and then head to your stand, but as someone else alluded to, drag it 20 yards on the upwind side of your stand, and then hang it 3-4 feet up a tree 10 yards passed where you wanna take your shot.
Spray your pants and boots liberally (scentblocker or scentlok or not) with a good scent eliminator before you get to the spot you want to start the drag, then once you get there, put on your rubber gloves, and spray them with scent eliminator also. Dip your drag in the scent or (even better) lay it on the trail and pour the scent on the drag (this gets their attention a little better, but you waste a little scent.) Tie the drag rope to your foot and walk slowly toward your stand. Try to prevent it from snagging on trees, branches, logs, etc. You want to leave a very "followable" trail.
While it's probably not necessary, I freshen mine up every 50 yards or so, by dipping it back in the bottle, or again pouring scent right on the drag.
Also, kill an old buck before he gets to the drag hanging in the tree. I've had them turn inside out when they get that much scent up their nose and there's no logical source for it, i.e. deer :mg:
And I know it sounds silly, but wear rubber or plastic gloves. Chances are you can get them somewhere. Heck, your local grocery store meat dept. or deli might even give you a few to use.
I use various scents, but I started using a local company a few years ago, and have been very happy with it. I figure it's fresher too.
Good luck, and send me a PM with your results.:darkbeer:
