re: Buck bombs / scent attractants?

Which ones yall using? Never had any success with the doe estrous or dominant buck ones. Used the acorn one quite a few times and that one at least brought in a bunch of squirrels one of the times I used it.

Came across a scent I hadnt seen before, sweet corn...gonna try it out.

Do you normally just set the whole bomb off at once or spray it little by little around a bigger area
