I was looking at these lights and was trying to decide on the best model for general illumination considering weight/size. The 3C looks pretty nice but the 2D appears closer in size to my PT Surge that I use alot(even with 4 batteries). Uses would include: walking dark trails at night, docking boat at night, walking dog, hauling wood in from woods, general camping chores, etc. Any personal experiences or feedback would be appreciated /ubbthreads/images/graemlins/smile.gif.
