If 34x34 isn't enough to get you up those hills, a smaller ring combo up front (probably requiring a new crank) will probably be the ticket. Spinning out in high gears is really not an issue. Even with a 46 big ring, you don't spin out until 40mph -- at which point aero rather than your ability to spin the pedals is what's holding you back.
Do you really do this- 122rpm at 40 mph?
For me, it's possible, but what's the point?
