Ive been lurking here and decided to join y'all

Its a done deal- the bike is home in my garage and definitely non-returnable so... but I just wanted to torture myself and hear your opinions on whether I made the right decision or not.

My LBS had a sale- I was set on the Dolce Comp but they were selling the Ruby Comp for only $300 more. The Ruby was a SWEET ride but the posture I had to assume was fine/good but not perfect. The posture I assumed on the Dolce was perfect. Stem is longer on the Dolce and not adjustable vertically on the Ruby. I kept alternating between both bikes, really wanting the Ruby for its handling and carbon frame (Im a tech geek so I like the upper end of stuff) but liking how I rode on the Dolce (more of a touring posture). After two hours, I finally decided to take the Dolce home because I'm just a recreational rider who recently got back to biking after losing 85 pounds (75 to go).

Did I make a mistake and should have taken the Ruby home? Would I have grown into the Ruby? Will I end up getting rid of my Dolce and going Ruby a couple of years later? Im just wondering... ARGH.
