Well if you want to limit yourself to 30 yards, cool! I have no problem tagging a buck out to 50 yards and more. I hit a buck last year 45 yards away and knocked his feet out from under him, he fell like a rock. but then again, I'm shooting heavy FOC and it's nothing for me to shoot 600 plus grains... I'd rather have my broad head pull my arrow than my arrow push my broad head. I'm not a newbie, I've been doing this over 40 years. I just don't like gimmicks, see too many guys waste money on stuff that does not make them a better archers.
Just my two cents worth.
So many guys watch hunting shows using stuff that most people don't need, but if the vendors are paying to be sponsors, they will use it.
