if you are using trilene xl in the rocks it isnt very abrasion resistant,try 12lb big game or bps excel i use both and dont have a break off problem.remember as far as weight braid is thinner and sinks better than mono unless you are in current you can drop down sinker size,braid will make it as if you are using a bigger sinker and it will hang easier because of the lack of lift from the line.no pro either just my experience.
