Hey fellow archers! I recently purchased a 2010 Sabre from a local sporting goods store. They told me that I could change the draw length modules with out a press. Looking at the module screws, they cant be accessed with out some rotation of the cam. I just wonder if the guy knew what was speaking of. Also, Im having trouble finding what module is for what draw length. I have F1 through F7. There is a F2 installed now and it seems extremely short. This is the first compact bow I have owned and I could use a little help, if possible.

Thanks for your time.
