I used to throw my A rigs on 65 lb braid but the last year or so I have been using 20lb FC. I've often wondered if 20 or 25lb Big game wouldn't be just as good or maybe better. If I'm throwing the A rig I'm usually using 5 1/8 ounce heads with 3.3 to 3.8 inch baits. Not trying to reinvent the wheel but I can't remember the last time I broke a fish off on Big Game.
I usually have it on a flipping stick if I'm fishing around a lot of hard cover that I think is too thick for FC.I buy a spool every year to fish one lake that has a lot of bushy trees that usually has a really good flipping bite.
