They are pretty good just remember to bring a tie down. My buddys son plays offensive line for the University Of Tennessee and he hauled out 5 deer mostly uphill with a little help from me.
I personally find it easier to tie a deer off on a pole and walk it out if there are two people...
I have done the Pole thing for about 20+ years, [:'(][shoulders get sore on the second deer and always carry the heaviest one first] then a one wheel cart[better than a pole]....then I added power,

the only way to carry!
