You can use a longer arrow and cut it down for a CB with no problem. Three things you need to remember though. One is you have to make sure you keep your total arrow weight up as to not damage your CB with a dry fire affect. Second is most CB's take a extremely stiff arrow, some of the Vertical crowd carbon arrows have a low spine and you can have stability problems. Lastly the diameter has to be the right size or the arrow will sit to low or high in your rail and you can have string jump issues. That is where the string hoops over or under the arrow as it is shot, not a good deal! So it can be done, them are just some of the biggies that come to mind.
