sorry in advance if I repeat some ones coments as I didn't read them all. I have been baiting in ak for the last eight years. the first thing I learned was the more bears you get on your bait the more other bears will find out about it. if you have time let the firs one or two hit it for a while before you hunt hard.
I do two thins to make this happen, I take a grease jug and poke some holes in it and go for a hike in a clover pattern from the bait. several hundred yards out then a couple left or right and then back to the bait.
the second step for me is to saturate the soil with grease so that when the dig or step in it they track it all over the woods leading back to the bait.
the third is hang a jug so a average bear can just reach it. I poke a small hole each time I check the site the last just a little lower than the previous. this way hopefully the first bear will grab and bite the jug dowsing him with stink so he can spread it anywhere he goes.
I have noticed it takes 3 to 8 visits for a bear to get used to humans being present. they are not stupid, the probably know you are there, so every time I check the site I will leave my shirt in the stand, same goes for when I hunt, if you are a chewer leave a dribble of fresh dip when you check or hunt, the will get used to it.
as far as bulk bait use what ever is cheapest or the least difficult to transport. I like fruity cereal, the Costco kind, light and cheap. they will actualy taste fruity if you let them eat long enough. I try to leave a lot at first then when they are frequently hitting I lessen it to about 2 gal a day and I make some noise when I bait up before sitting.
I like to hang some tin cans around the barrel and other bait areas so that they make some noise while feeding, that way other bears hear activity and I can sit and listen when sneaking to the stand.
they will get to where they hear that then the younger ones will be less patient for dark and the older ones will give in when they hear the others eating.
after all of that rant I am not saying forget the wind as you may tag out quick in the right conditions but a close stand set to me could be worth the wait, I mean 10 yards or less, I have shot them at around 5 to 3 yards, talk about a chip shot.
my best piece of advise is use a trail cam know what bears are hitting and when and use all the time you can as you will get to have some unreal time watching the ones you shouldn't shoot when you know what you should.
