<p>Thank you for your replies, yes I do feel that the 100mm is 'the one' to go with. Of course as I already have the three lenses I quoted, it would be easy to use just one for a month or two, then another and finally the third and see which one liberates my photography and which constricts it, therefore this is what I will likely do. If I actually had no lens yet and could only afford one I think it would be the 100mm, it is after all rather special. So I guess I have answered my own question, then again it wasn't really a question to myself, I'm leaning towards the 100mm anyway, I'm just curious as to which 'one' of the three lenses other folk would choose.</p>
<p>Kind regards, Simon</p>
