Depending on how much drag you are planning on using I would put on 65 lb.
I have 65 on one of my reels and 80 ono another. Especially into the wind I can cast a lot farther with the smaller diameter. I don't plan on running more than 25 lb. of drag on a spinner.....
Thats why I said it keeps you honest. I also guess you wait till the lure lands before you close the bail too
This gives you an overestimate of the distance. That is why some unrealistic anglers think their lure has landed 100m when they have 100m line out and many times I've read anglers using a line counter on the reel to cast and check their distances.
The reason is when you cast the lure travels in a parabolic curve and the line out of the reel is the path of the parabola and this doesn't indicate the range!
Actually how far do you reckon you can chuck a 100g lure using 80lb line using an 8ft popping rod? I've read some distances achived and to match that I need a bloddy full tournament pendulum to send that popper that far!!!
