I need to replace the string on my 09 Martin Cheetah. The specs on the sticker as well as on the the website call for an 85" string. When I removed and measured the string it's actual length is 84 1/2. I have another 09 cheetah and measured the string on that and it is also 84 1/2". What performace and or specification changes will happen to the bow when I put on an 85" string?
