Hey, in my experience the straightness does play a factor but what helps out the most is the consistency of the weight of the arrow. Just remember, if you are shooting less than 60 yds you won't notice the difference.
Well I hunt spot and stalk, and that deer right there makes me want to have the patience to stay in a stand. A friend of mine told me that a stand is the way to hunt the big bucks.
Congrats!!
