The new Exceller LT - Daiwa uses a carbon fiber body called ZAION V. The new version is 3% - 5% lighter than our current Exceller for comparable sizes. It also comes with an airdrive rotor and an airdrive rail like our version on the Exist - are tubular, but they're not on the Exceler. We chose a solid underwire for its rigidity and bending strength under normal use. The thinner, smaller wire is also lighter, which reduces the weight of rotation and thus reduces the weight of the spool. The machined aluminum handle is a comfortable, strong connection to the main gear of the spinning reel. And the converted Exceller is extremely smooth with 5 ball bearings and 1 roller bearing to maximize performance.
