Parker bow question
 

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?

It's really not worth cutting an inch off your arrows unless you are trying to stiffen them up.
