Yes I would prefer a double. Save on weight for one thing. I have been to 6 different LBS and my thought is why do I need to pay such a huge mark up. When I previously sold cars, people would make offers all the time that I thought were ridiculous. Sometimes we would sell at their price though. If I offered 600 on new specialized and the LBS could still be profitable, I don't see how this would be offensive. Its my money, if they want my business they need to meet my needs and price part of that.
