No dog in this hunt, but I'd suggest you might want to read some of John Barsness aka MuleDeer here at the campfire regarding "Pressure Signs". Seems according to John's extensive studies the "typical" pressure signs you're referring to may not be all that trustworthy. He'll also point out that the sign you may wind up with may be real sudden and real unpleasant when it demonstrates itself. Personally do what ya want as I don't think you'll be anywhere near a range I frequent, but ya might wanna take a gander at some of John's findings.
