I use an AbuGarcia Ambassadeur C4 The big one 6601C4.
The gear ratio is 6.3:1. I do not use the 18# however. I use th 15# non-lead. I started using that line when the lead weights started getting banned. I just figuerd the leadcore line was next so why not learn how it works now... anyway back to the original question. This reel will hold all ten colors with I don't know how much 20# braided backing, but barely. I love using this in the spring when I only let out 3-5 colors. I usually catch more off my lead rig than my riggers early. However, as the depths get deeper and the more colors go out the high gear ration does not seem to want to pull in all that weight. 7-8 colors just becomes a chore to reel in to change lures or go home. It still handles the fish just fine but I think I want to pursue a reel with a 5. something gear ratio.
