I think your broad head is way to light. Go to at least 90gr or better yet 100gr. The speed will not do you any good if you can't hit the mark. If you still want the speed thing go to a lighter shaft. Gold Tip has a new shaft out the might fit the bill. If money is not a problem you can change to the arrows I mentioned , 2" blazer veins, and a 85 or 90gr head. Personally I don't think it is necessary. This set up will increase your speed about 8 to 10%.
