Is the only difference between the citica G and the curado G the spool??

what additional stuff is on the chronarch E that isn't on the curado G ?

And please don't tell me to look up old E series. I never looked at them and they aren't on shimano web site anymore.

Is the citica G better at anything than the curado G, for that matter is the curado G better than the chronarch E at style of fishing?

The spool, the brakes, the crank shaft bearing, guide, and maybe the drag. The Chronarch E is a totally different horse.Citica is a great reel for intro users, Curado a bit better, and the Chronarch......well, that is sweetness.

The Shimano site has a cool feature where you can compare specs of current reels side by side. Check that out for feature and spec differences between models. Technique wise there isn't anything you can do with one that you can't do with the other model ina similar gear ratio.
