I've a Dinotte 200L front light ( I hope to upgrade to more lumen's ) and the Dinotte 140 tail light which I like very much, as well as a Princeton Tec EOS on my helmet which also works well for me. For my area, I'd like maybe 600L up front which I believe would allow me to see far enough down the road that I won't out run it's beam.
In your case - your Princeton Tec is probably the light that helps you to "see" the most.
I'm not familiar with the beam from an EOS but if you added a flashlight with some throw - instead of another expensive all purpose light - you may find that the Dinotte 200 is all the "general light" you need
