Jelvis,
Have tried slamming the tine several times but only with limited success. Seems muleys don't get into it as a hard as whiteys. On one of my Muley Crazy videos they show some good rattling action, but they say it's tough to get the big boys to come in.
I do use the rubbing antler and burping pretty much from the end of oct through the end of the season. I rub a lot. Sometimes I use the barrel of my rifle if I'm not carrying a shed. Have had tons of big bucks come in over the years. It works well in the thick crap where you only can see 20 metres in front of you. You bump a buck and just get that image of asses and antlers and you start pounding on a tree and burping, that buck is going to turn around and come and kick your ass. Works well with does too. If you bump some does and you don't want them messing up the deer beyond them, burping and racking calms them down. They'll allow ya to just walk on by.
As for scents, I only use the natural stuff. I'm too cheap to buy the store bought stuff. I find where a doe pissed in the snow, and I'll rub my legs in it. The first buck down in our group, I'll grap the tarsels and rub them all over me. Sometimes I'll just pack that sticky tarsel on the outside of my pack
