Thanks for the reply mickey, the easy troll is rated for 8 pounds, I don't remember the weight of my ball, but I guess 6 lbs. I'll probably go with an 8, but don't know the best shape, ie pancake, or those fish shape things I've seen.
The chamberlain works great, It's adjustable down to pretty light pull, I keep mine with the adjustment screw turned out 3.5 turns, which should give me about 0.8 lbs to release it. The small lakers sometimes don't trip it, but salmon usually do. A lighter setting doesn't seem to get as good a hook-up ratio. My rod has 20lb power pro which also helps.
Being an in-line brings up another question about balls. Is there a shape that is less prone to the side-to-side track the ball does. I assume the pad type that attaches to the rear of the ball tracks straighter. Anyone try the fish shape weights?
I hear ya on getting hooked on fishing LO. I fish saltwater and fresh, and there's only so much time to fish. The only cure is more fishing...
