You gotta go with what is working for you Engman. If you have a formula that fills your tag with animals you are happy with, what more can you ask.
I think a lot of the problem with peoples views on scrape hunting being a "waste of time" is that they are not hunting the right scrapes. Just as DKO explained a little on the different rubs, such as the sign post rubs(generational) that ALL bucks make, there are different types of scrapes.
The Hot scrapes made by DOMINANT bucks, truely hot scrapes, are VERY VERY hard to find. If you find a likely looking scrape and just decide to set up your stand there, you probably would be easting your time.
But if you find the one big boy left yesterday, and checked again this morning, then you should camp your @ss out there daylight to darl for the remainder of the week, and you just may have yourself a wallhanger, not just a buck.
My earlier comment about only the dominant buck "will last" on this scrape line.....when you find the scrape line mentioned above, after you kill this brute, you will notice the cuts and gashes over his eyes, and the knotts in his neck.....he will be exhausted from kicking butt on every single comer that dared interfere with the little game he is playing with the hot doe he found 3 days ago. He knows she's about ready, and will check in 2 or 3 times a day until she comes in........will you be there?
Like you said Engman, this is what works for me.........I have tried and tested it for close to 3 decades, and have killed over 250 whitetails(VERY LIBERAL bag limits in the south), and a great many that some would label Wallhangers.........if it ain't broke , don't fix it.........
.....but I most certainly do acknowledge that you and everyone else should adhere with what works for you in your respective areas.........
.....good luck to you all in the coming season!
