I have used a fly very similar to the Grasset Minnow.
Bead chain eyes
white maraboo tail
pearl estaz body
EZ tie and it also works well for lady fish. I fished it right along the surf line/sand at dawn. I fished at Navare which is just west of Destin. Tie several in different sizes or take your fly tying stuff with you. You may need to match the hatch so to speak. Have fun
