I use the regular one! At twenty feet up a tree and shooting out to 30yds exact I aimed for a leaf on the ground and hit it. I took a deer out at 38yds that I ranged at 40yds. That is due to me ranging the ground where the trail was no the deer itself. Short yardage is no difference, I have shot leaves before leaving the stand, something I do, straight down with no difference, but my form stays the same, and I bend from the waist.
