Harlot,
Is there anything you particularly like or dislike about the Raleigh? That may give you a bit of insight into what you'll be looking for in your next frame. If there's someone that rides close to your style, check out what they're on or ask them the same questions.
When you're looking for the next step, I think you should start looking to personal preferences. You want a machine that compliments your strengths so you don't have to compensate for them.
