OK Ladies. Test rode the Ultegra & Ui2 today. On bikes I wouldn't buy (trek, specialized tarmac-they had in my size w/the gearing I am looking for). No big change in terrain available, mostly flat with a little iddy biddy bridge.
This is what I found:
Ultegra
Felt familar-style of handle (so change gears and apply break without moving hand)
Smooth gearing (had apex before)
Could feel change on front derailer when switching back and forth (not problem, just more obvious than Ui2)
Changing front derailer I would push too hard on gear and I would swerve a little
Ui2
Very fast
Front derailer change happened smoothly
Have to move hands a little from gear changing postion to break position
More confidence when I switched up and down fast when needed
Cost $1,000 more! (for a frugal person, hard to justify need v want even if my husband says it is ok)

Will sleep on it. And post back my decision and experience with new ride.
Thanks so much for all the feedback ladies
