New thread in the General section called "PFS anyone?". Some good info there. In a nutshell... They are more challenging and require a specific technique, but once mastered are as accurate as any other frame. They are the ultimate in pocket friendly. They open the door to things you never thought could be turned into a slingshot. Lots of really cool designs. To me they just have a big coolness factor. In the end they are just another option in this awesome hobby.
