A good 'crossover' rod / reel combo?

[bubblehide]

With spectra and topshots (that you can easily change out), you can do a lot with one reel. I'd say all those reels would do what your asking; after all, from 8 to 20# line, is not a big range at all, and I've often used my now older Calcutta's in just that way. But you may want to be a bit more paticular on matching it to a rod for your intended target.
