Hawgs BF Rut, synthetic "doe in heat" scent, to my nose smells like the regular in heat pee you'd buy but lasts. We used it and BFgland to create a mock scrapeline last year and the area gothit pretty good bybucks. I don't put a lot of faith in scents but the hawgs seems to works as good as any real stuff I have tried in the past.
Haven't tried or seen code blue stuff up here so can't comment on it.
I use ob unscented tampons as scent wicks...I steel them from the wife a few at a time throughout the year
! They work really well, just take a 35mm film canister put some of the scent in and drop the tampon into it. They swell up, so don't try dropping it in via the bottle top or you may end up with some smelly stuff on you. Though due to the swelling they really catch the wind.
I wouldn't dare ask the wife to supply me...yuk!!! I have heard of guys using the soiled napkins as well, that is way over the top for even my addiction[
