I have been wanting a X-bow for some time now. I am looking at the high end x-bows with the higher speeds. One thing has me perplexed though. Say you have a x-bow that shoots the standard bolt at 350FPS. Then you have a speed bow that throws a arrow at 350FPS. How do the two compare at say 30 yards, 45 yards, 60 yards, 75 yards ect.? I can shoot a bow pretty dang well for as little as I have shot so I wonder why by the x-bow over the regular bows? I don't know why, I have wanted a x-bow for years and years. So what is the advantages and disadvantages of each?
