95% of the time I fish weightless usually wacky style, but take into account the worm could weigh up to 3/8 oz or more.
The two casting rods that I currenlty have are:
G. Loomis BCR803GLX, St Croix Avid 6ft 8in, both tips are extra fast for the senko toss.
Now just as important is the casting reel you would use. I have a Daiwa Steez and the Shimano Calais100 and they both work really well, both loaded with 30lbSufix braid. I have tried a Daiwa Fuego, and a Abu Premier and they do not excel at casting lighter weights. The Chronarch MG50 and the core would be great also.
I am now using the Steez with a 10 1/2 ft Avid for floatfishing. It floatfishes and casts very like a dream with only the weight of the float, roebag and splitshots.
