Considering the Evenflo Symphony LX - just returned the Cosco 65 because the crotch strap dug into 2 year old chubby thighs. Is the Evenflo strap long enough not to do that?

Hello - I am curious whether the Graco Extend2Fit and the Graco Size4Me 65 are the same frame/structure?
The Size4Me performed very well on ConsumerReports.org crash testing - but the Extend2Fit was not tested.
I would prefer the Extend2Fit - which allows longer rear-facing - but only if it is the same safety-wise as the excellent Size4Me! Thanks!
