On motion capture analysis, I'm also "flicking" the back of my knee on the upstroke. So the pedal stroke is not smooth.
I guess I'm torn between the 58 and the 61. Since neither one fit super well, the most appropriate action is to get fitted for stack and reach on an adjustable bike with a fitter. If only I didn't have to wait 2 months.
Get on any other bike and figure out your seat height as best as you can. Use a plumb bob to get the fore-aft the same as the Cervelo. I'm a little bit shorter than you and I could ride that 61 provided I could get the bar high enough.
