You put into your profile whatever you want others to know about you. If you intend to ask questions about balls and layouts that will work best for you, then it's a good idea to include info on your PAP (positive axis point), your average ball speed, your style (stroker, tweener, cranker), low track or high track, etc. Anything that helps a reader understand how you bowl.
Most people also include their current ball lineup. This
is ballreviews.com, after all!
