what is the best colors in your opinion to catch big Mr. B on.

There 's no such thing as the "best" color. Silver for clear water; gold, copper, black, firetiger, hot orange for murky, colored or muddy water; which doesn 't mean that the selection is strictly like that. It 's the vibration what attracts the fish to the bait.

My primary experience with in-lines is in the fall while fishing for white bass at Lake of the Ozarks.  One of the guys in our group makes his own in-lines and paints up lots of different colors.  When we start fishing we each use a different color (maybe four or five of us fishing) until somebody starts getting bit.  That night he will make up a bunch of that color for us to use over the next several days.  Over the last few years, the color has varied from white/red, yellow/orange, bright purple, puple/green.  You just never know.  Also, as the day goes on the color may change again.  A lot of people don't believe in color, but I do.  You just have to experiment.

I dont really use in lines for bass, although i do fish inlines in streams for  trout, and hook up a couple smallies here and there incedentily. The color that works best for me is the rooster tail bumblee bee yellow with the yellow skirt.

As for big bass fishing id stick with the spinnerbaits.
