I understand that dead is dead, I Just thought it would make sense that a speed bow should be faster.  
The reason i was shooting 7595's was because the guy at Scheels gave them to me after i decided what arrow i wanted, I didn't realize i was shooting 7595s til a few days later.  
I was thinking that the arrow i was shooting being 400grains + the tip would be 500 grains, and that just seemed a little heavy. 
And I had another question, does a shorter draw increase speed, I just had mine adjusted again it was a little long.
