Have to agree with Kodiak, and you probally won't notice a huge gain of speed but with all (hopfully) still in tune you should be fine. If this bow feels good and shoots good why worry with change I still have my 1st bow I bought with yard mowing money, and when I feel the need to go down memory lane I get it out and run a set of shafts thru it for kicks. All of my bows have been handed down to my boys not out of loss of shootability but because something new caught my eye. Weather it was1 yr or 15 yrs.I have done both.
