A 5 wt. will work fine Arkmay! I generally use a 6, 7 or 8 wt. rod depending on the size of fly I am casting. For Sandbass, a 5 should be fine. It can be real fun when either Sandies or Hybrids are schooling on top with a floating line. To get to them down deep you'll need a sinking line or sink-tip line depending on how deep. I use a fly rod quite alot.
