Tire noob in search of advice.

[AdventurousGentleman]

To begin, I own a '77 CB750K, it is my daily. Any time, any condition. I ride atleast an hour or two a day, as well I am planing a 1000 mile trip. I also like to curve some twisties.
Currently the bike is running these (dunlop 404's) 100/90 19 on the front as well as 130/90 17 on the back. As I began to research and plot my new shoes, I am now lost.
Radials or Bias Ply? What should I be looking for? is there a way to get everything I need in a tire? Really any and all opinion and advice helps.

The Dunlop 404's are the recommended tires for your bike. Stick with them or...

My 74 wears Bridgestone Spitfire S11's because I wanted the raised white letters and it's practically the same tire.

Either one is a good "all around" tire which sounds like what you need.
