i prefer a dead release.
get to anchor- at least two anchor points,good back tension!! pause, steady everything up, and then sub consciously relax my fingers, my draw hand and my bow hand stay exactly where they were at anchor, as my follow through, until arrow impact.
everything as quite and still as i can- also helps not to flag the animals too!!
if i use the push pull, i find there is too much movement, and my accuracy suffers.
but hey, its whatever works best for YOU!!!!
