Bear in mind that at some point road bike sizing became just as arbitrary and unpredictable as MTBs -- as soon as compact/semi-compact/sloping top tubes came along on road bikes it all got a bit random. Sometimes you'll get something that's essentially a 58 in terms of reach but is called a 54 because that's what the seat tube measures. Or the same bike might be called a 58 despite the fact that no part of the frame actually measures that. Or it might just be called L And even if they use the same dimension to describe the sizes, two 58s could vary widely in reach and bar height.
Old frames with traditional geometry are more consistent. At 5'11" I'm thinking you'd be in the 56cm/22in area or thereabouts.
