If i recall your previous posts (you ended up with a Rock Mountain Instinct, yes?) I will venture to say, judging from what I've read, that you suffer from Analysis Paralysis which has now manifest itself as Buyer's Remorse.
Never fear, Analysis Paralysis is fairly common, I have a sister and a co-worker who both suffer from severe cases. i.e. It took my co-worker 5 years to research and purchase her current car, a Prius, and she regretted and hated the car for almost a year after she got it (now she loves it). I won't bore you with the details of the multi-year saga of her selecting her current Nikon camera (which she also hated and now adores).
I suggest you follow ridelikeaturtle's advice and ride the bike, at least for one season, then review your decision.
