Decision made...I'm getting the SM. I was gonna wait til Saturday to test-ride a Bonnie and then decide but I really want a Speedie. I realise it'll take a bit of getting used to, but, let's face it, so do most new things at first. I'm just gonna find a quiet car-park and practise going slow.
Thanks for your comment, guys. I'm sure I'll have plenty more questions in the near future and I do look forward to, perhaps, seeing some of you (UK-based) out in the real world.
