Good Braid for rocks?

[NIB]

When I bridge fish I use 80 lb braid(kitestring) an 40-65 lb leader depending on the water clairity.I have used a uni to uni to make the connection.Never ever had it fail on me.I have had times when hung up it took 2 of us to break it off.This is extreme fishing in a 6 kt current.
For rocks i have pinged some 30's off the rocks with Fireline I have broke about everything else.
Skitter u can tro 30 lb mone on a conventional.But its to thick for spinning.Try 20 lb or even 15.Guys like ande backcountry.I have use big game for yrs. Last yr i dragged a 34 lber around a rock with it.it took the bait an went down i fought him the whole time around the rock on a loose line when i killed him a dragged him back.
