You didnt ask for it but I think your main line weight is to light.
I would step up to 50# braid. I would down size on the leader a bit to 60 or 80 # floro.
The knot I use to connect main line to leader is a slim beauty.
My leader to hook has been a loop knot.
I havent had either fail on poons in the 140# class.
Just my opinion.Capt. Steve Betz
