I have used the cardinal 102 which has 20lb power pro on it at the lake near wichita falls, it has caught 3 10 lb catfish with no problem, it can hold 130 yds of 8 lb mono / 30 lb power pro---the diawa 7.1 sh can hold 150 yds of 12 lb mono or 50 lb power pro. My question is, since these are not big reels will it damage them putting this large of power pro on them? I had thought that either 20 or 30 lb power pro on each would be O.K., putting 75 yds on each one, would this be O.K. also what size mono backing should I use?, if I use 8 lb mono will that still provide strength for catching a big cat?, or does the mono weight have anything to do with the power pros strength? I read that 50 to 75 yds was usually enough braided line for catfishing?
