So, does the size of a casting reel and how much line it holds important for most bass techniques? I can understand having a larger size reel if you are salmon fishing or something similar where you would expect big runs because you need more line just to make sure you don't come close to getting spooled. But this really isn't a concern with most bass/walleye fishing. I would think that if you have a reel that holds 120 to 140 yards of 12 pound mono, it's more than enough. Why would anyone put up with the additional weight of say a 150 or 200 size reel instead of a 100 size when it is not really needed?
