look, you need to do some testing/experimenting on yer own. ain't nobody can armchair quarterback what will or won't work for ya.
get field points from 125 to 250 grains and see what flies best for ya. you can also use glue-on field points and different adapter weights.
then use glue-on broadheads and a weight adapter to best match the field point weight that flew yer arrow best.
i'll add ...
you wanna find an arrow that flies the best. don't be too concerned about the total arra weight or the foc or whatever, just as long as that total weight is not much lighter than 9gpp (grains per pound).
if your bow is truly scaled 42# @ 28" and you are pulling 28", then a 420 grain arrow is 10gpp. a 380 grain arrow would be the lightest (9gpp). heavier is always better, but you need to consider arrow trajectory at your expected hunting shot distances.
your hunting will be lethal as long as the arrow flies well, the broadhead is sharp and you can confidently place the shaft in the critter's vitals.
so, there is no fast food answer, you need to work on this yerself.
good luck!
