for those who know parker a little better than I. I am going to change my moduel from a 31" to a 30" and need to know if there is anything that I need to do with the string? I just replaced my broken 31 module with a new one by myself without a bow press, but I am going to toy with the 30" and need to know if there is anything I should do with the string or cable?

Also, should I get my 31" arrows cut to 30" if I plan on keeping it set to 30"? Will they fly better at 30 than at 31?
