What Marc Irwin said.  

I'm using 46/30 with 11/28 (8s) and I find I spend a lot of time now in the 
middle gears.  I tend to front shift at stop lights now:  I shift 46->30 in 
one of 2 or 3 middle gears, then shift 30->46 once I start to roll.  

This is a relatively new system for me (I previously ran a 53/39) and it's 
taking a little work to get out of the mindset that I was previously in.  
The 30/28 really is as low a climbing gear as I can imagine for the riding 
I do around here (Connecticut).  And while I never, never, NEVER thought 
that I would use an 11t cog, 46/11 is nice to have at times (e.g., on 9% 
grades).
