I would get rid of the versatip, it's a single hand line and if you got the 9 weight it will be way too light for a 9 weight switch and no good for spey casting. For spey casting fishing heavy tips and bigger flies you will need a compact or switch skagit line or for smaller flies and lighter tips a compact/ short scandi line. The skagit is not much use for two handed overhead casting (you will not be able to single hand that rod comfortably for long), the Scandi would be ok or maybe a 10 or 11 weight Rio Outbound. If you are targeting springs and chum I would get a compact skagit head, you will also need this to chuck tips and big flies for steelies in the winter. I can't find a grain window for that rod but 575 to 625 grains should be about right for a 9 weight switch but you should email Cabelas and see what they say. You will also need to buy a running line to attach the head to and some material to make some tips out of, am sure Michael and Young could hook you up with all the info you need, there is quite a bit to get your head round at the start.
