well lots of possible options as you listed
but to me, I would just how your getting in, and just avoid walking in the scrape
feel free to hang a cam over the scrape if you like, never hurts to see
I have seen BIG buck and little bucks all use small scrapes, as well as Big scrapes
size of teh scrape to me doesn't always mean size of deer, and most scrapes get used by several different bucks too
I have used a leaf blower to make trails into or out of stands in the past
works great but can bite you in the butt as deer start using them on me all the time, making them slip in on me without hearing, so?? it happens
I still use same trails, I just be very very scent free as possible, spray down boots for sure
but I would say keep going is as before, just don't walk in the scrape, MAYBE if you like scents, every time you walk by add a few drops of something to it if you add a cam over it??
