If your worried about string jump, use aheavier arrow and really quiet down your bow. I wouldn't worry to much about speed and arrow drop. Especially inside 25 yards.My guess is that you could group thenew arrow setups exactly where your current arrows are hitting. 10 grains will not make a noticeable difference inside these short hunting distances.Atleast not for the average bowhunter like me, I'm no Olypic Archer...Thats for SURE!
Heck i can use one pin to 25 on my bow and im shooting low 270s with my 481 grain arrow.
IDK if there is a problem with your weight or not, I would personally change it simply because of warranty issues...But then again, if something messes up, whos to say you didnt use arrows over 5 gpp?
