Did you climb and descend on the Litespeed? I'd want to compare how both bikes handle. I wouldn't buy a new bike based on componentry, as you can always get change that out on your Ruby. Also not sure what you mean by the Litespeed being more "compact.". Do you mean that the top tube is more sloping? That the top tube length is shorter. Have you compared the geometries of both bikes? Any significant differences.

Ti and carbon are both great frame materials--if the bike fits and handles well.
