The original Shakespeare Sigma Wand set the benchmark for these type of rods. I managed to break the built-up ferrule on the top of the carrier section on mine, so I ended up cutting the base of the tips back a little bit so they would fit. Although this reduced the casting range, it actually improved the bite registration and playing action of the rod by making the action even more mellow than it already was.
Another excellent rod of this type that I don't use due to its rarity is the Shimano Diaflash Winklepicker, perfect for straight lead fishing in a bit of flow.
I also have the Cadence Wand, which is the nearest to the original Shakespeare that I've come across. Very sensitive but limited to still/slow-moving waters, where it excels.
The latest of this type of rod that I bought last November was a new brand for me. Cresta Blackthorne Pro-N-Feeder cover a range of rods and actions from light 9' up to heavy 14'. I've got the light 10' which is all carbon with three tips of 0.5, 0.7, and 1.0oz. Perfect for dropping the straight lead on the stick float line when the roach start to get a bit unsettled by the repeated disturbance of striking on the float.
