i use hi-seas mono also, the 25lb is great. on my channel cat tourney rods i run that cheap zebco braid from walmart. 50lb test. i really like it but have never caught a fish over 20lbs on it. you can really never go wrong with power pro, what sucks about braid is no matter what brand you go with you are going to pay for it, thats for sure. i would buy a cheap spool first personally to see if you like braid. then upgrade if you like it, personally i dont like braid but lots of guys love it. kind of an expensive spool to take off your reels if you dont like it
I don't like any mono over 20 lbs on the 55 and 6500 Abu's unless it's as a leader. I've been using Suffix 832 30lb on the 5500's with a 20lb mono leader. On the 6500's 40 lb Suffix 832 and a 30lb leader.
