Kayak ?

[MWOOD417]

Just got the itch to get into fishing from a kayak. I am about 5'9" 185 lb.
Would mainly fish for smallmouth and walleye in MN/WI area. I would like a
kayak that could handle medium to larger sized lakes as well as shallow rocky rivers.
Been doing some research on the Wilderness Tarpon series and Malibu kayaks.
Sounds like a rudder would be a plus for the lakes , Could a rudder be easily removed for shallower rivers ??
Any thoughts would be appreciated.
