Catfish reel size? Braid color?

Im not to familiar with those models from Penn, but I personaly love peen reels for catfishing, a Penn 550ssg Spinnfisher Graphite should be more than enough for the biggest cats. Just make sure you use a quality pole and braided line. Also make sure your leader is not braded bc even the small cats will shread it once hooked. Braid color shouldnt matter if you cant see through the water, but you cant go wrong with green.
