Hey Ya'll...newbie needs advice!

Hey guys, I'm new to metrics...I've been into American V-twins for the last 5 years or so. Choppers and Customs mostly, anyway I recently got turned on to Cafe Racers, really dig the style and at the same time looking for something as a daily rider to get back and forth from work and scoot around the city. So I've decided I'm going to build a Cafe Racer for my daily rider. I want to use the Honda CB750 as a base, thinking about an early to late 70's model. So my question is there any certain model or year that is better then another year to build off of? Maybe some years have better handling then others or better drivetrain/engine then others? Any help would be much appreciated.

Thanks
Ace
