I was lookin for some input on the C-4.Has anyone used them and how did they perform with the 6.3:1 verses the C3 with the 5.3:1. Seems like with a bigger fish the reteive ratio might be a little fast.I was thinking of getting a 5600 C4 because I like the thumb bar release verses the release off to the side on my 5500 C3.Thanks for any input...
