Personally, if you're fat rolling, my personal recommendation is to use the BK Shield. Reason is that the one thing that will REALLY cause you problem is Great Combustion and your best counter is an effective shield against it.
Next, your poise should at the very least hit 77 (You have a lot of weight for that), 107 is another good point for tanking a variety of hits and 124 would let you trade as many blows as possible with anything below a greatsword, practically; however, impossible unless you use Wolf Ring. So 107 should be your main point.
Also, make sure your defense is high (it is very likely you'll have it high if you have the poise, however), you'll be trading blows a lot and the main form of damage you'll be doing will VERY likely be in trading blows.
