I just re read your post about the line
I will spool it with 30lb braid, PowerPro is what I have used before on other reels and it is good. Some say that SpiderWire UltraCast is thinner diameter with same lb test (which means more line capacity) but I have never used it.
For flounder and slot reds 12-15lb line should be more than enough, unless there is a lot of abrasion (oyster, rocky bottom, etc).
I have used Cajun Red Line and it is pretty tough for a mono. It does have a lot of stretch compared to braid, but it is thinner than average mono in my experience. You could do very well with it too.
