I actually like it but it might make deerstand shooting tough.
He likes a wide base,even when swinging a bat.It has worked well for him there and he even gets great weight transfer doing it.His hitting coach liked it as well.I have a friend that isa level 4 archery coach and he loves a wide stance.
So,from a target aspect,no problem with it,from a hunting one,he might need to narrow up a bit.
