I am not a fan of drill tech. Unlike borium that has some give, drill tech has absolutely none and that can be bad on a horse's legs over time.
When I was hard trail riding, I used St. Croix Rim Shoes with borium head nails. St. Croix Forge Horseshoes - Rim Shoes
I have Walking horses whose strides are different. My senior Walker has a tremendous long reach, so I had the farrier use all borium head nails.
Another Walker has a shorter reach and never did slip much, so he would get a borium head nail in every other hole.
That combination was better than 4-wheel drive. No one ever slipped and no one ever came up sore.
These days my horses are completely barefoot because I don't ride like I used to.
If I were still sliding them down the hills, I would still be using St. Croix Rim Shoes and borium head nails
