Should I go with heavier arrows?

I agree with that statement muzzy man. Heavier arrows are better, my setup has been working for me so far and momma always says if it ain't broke don't fix it!! Lol I'm sure everyone momma says that lol

 

I was running the numbers with ke/momentum calculator and you definitely start losing penetration at a certain point. Though that point is pretty high, it's all a tradeoff. Since I s3ldom shoot long distance, flat shooting does me little good.
