I use 30 lb power pro on my downrigger and haven't noticed any diference in the amount of fish I have lost. I did have problems with the scotty power grip releases however. The guy at R & R tackle here in PA suggested a different release. I cannot for the life of me remember the name of it, but it is wired directly onto the cable. It comes in a blue and white package.... I'll track it down and post it here later. It worked great for blackmouth. I liked the fact that I didn't have the bow in my line from the rod to the release. I dont recall losing any fish that tripped the release except one to a sea lion. You twist a loop in the line and run the "pin" through the hole at the top of the twist. The pin locks into a clip that has an infinite tension adjustment. I worked way better than the gripper type release. I'll get back to you with the brand.
