ok i'v just resurched all this and so far i have found out that the order goes (or so i'v been told)
stella as the top
then the sustain
then the stradic of which i have got two that are both three years old and thousands of fish old and still working like new,
then the symetre that i have just brought one of,
then the sahara
then sedona and fanally
the sienna there are toher below that but they are then getting into the cheapes
i belive that you can't go wrong with a shimano and woule rather them then any other reels
