Re: 550ssg and 450ssg
I.M.O. if you plan on using braid, I would recommend a different reel.
I fish braid exclusively & had so many bad birds nests with my 450ssg & 550ssg that I sold them.
I also have a 4300ss that doesn't want to work well with braid. I use it just for squid now where I don't have to make any long casts (still have braid on it.
Braid is just too darn expensive to be cutting out birds nests.
Read a lot of other reports that said the same. In my experience braided line just seems to "like" the longer spools better.
Lately I've been using a Penn Sargus which has worked much better for me with braided lines. They're all metal, I like the all black look, & the way the loud drag screams when a striper is peeling line off the spool. Best wishes.
