Ive got one of the rods you mentioned. The 7'H Cumara. This isnt my choice for weightless plactics, however its my topwater rod and it is excellent. Like RW said, for weightless plastics I like a stiffer tip, I use a Medium Xfast to detect the subtle thump of a bass sucking it in. With the moderate fast tip on the Cumara however, you should still be able to cast relatively light baits, although I havent tried it.
