Share 'Springs or Screens that is the question ? I am ready to goo just dont know ?'

Hello all,   I am going to goo kit my grande I have everything I need I just want to know whats the best to do. I have the screen they give you with the kit. Has anyone used the screens ? Do they work as well as springs ? Anything I should know on how to set it up ? Or would it be better to use a spring ? Any ideas on where to get and what to get if springs are better ?   Thanks in advance. Robert
