I am in the market for an oilhead and want advice on what years and models to avoid or pursue. I presently ride an airhead with a windscreen and don't want a lot of "extra plastic" (e.g. RT or RS), though I am not a cafe racer or hotshot.

I don't even know if I'd want an 1100 or an 1150, so I'm looking for advice (opinions are valid only if they're backed by facts).
