Bigbulls said my arrows are well on the stiff side. What exactly does this mean? What is arrow spine? I do know you don't want an underspined arrow. Are overspined arrows ok? What else can I do to get thespine down? Can I cut my arrows longer? They are to the middle of my riser shelf right now ( at full draw). Sorry for all the questions just want my arrows setup right.

Thank You.
