I need some advice to decide what type of bike I should get. I will use it mostly for long ride, light trail, and fast commute. I own a CAAD 5 Cannondale but i can't stand riding 100+miles with this bike. My choice is to get either cyclocross or touring bike and it must be steel.

For long touring get a bike with some braze-on fittings to accomodate a rack. I have been riding an Ionic steel and a TiCarbon Dean on long rides like the BTC, Death Ride in CA, Seattle to Portland, and others. They are great light and comfortable for long distance rides.
This year I am getting my Dean all TI Compact frame fitted with brazons for a rack and VEE brakes. I want to be able to change wheels/tires and go from road to trail without any hassle. I am also working on a flat bar arrangement that can be fitted with aero bars (for 10spd campy bar end shifters) and CaneCreek Ergo barends. So far my experimentation has been yielding fantastic results and has reduced some of the pain of long distance riding with more and more comfortable positions. I am also using a triple which allows for easy riding the high mountain passes. Oh, and yes, the flat bars can be easily used out of the saddle with the Cane Creek bar ends for great leverage.
I have been an either/or Road/MTB rider and now I am adapting the best of both worlds for long distance riding.
If you really want to do long distance trail and road be open to experimentation to find exactly what you want. The options are limitless just don't think either/or.
