I personaly use a Saltiga Z40 'Ishidae' overhead and find it better than anything Shimano has on offer for jigging.Having said that,my mate uses a Stella and has caught a shit load of seriola on it (in excess of twenty fish some outings),over a period of four years he has had a handle bearing failure (not corrosion) as the only mechanical problem.It does however suffer from chronic corrosion under the various plates that adourn the reel inspite of a warm water rinse after each use.
Daiwa have done/are presently doing some prety good deals with various tackle stores........this could be the basis for the catastropic failure rate of the Stellas.....if you get my drift.
