WWW,
You might be a legend, but except in mid-summer you'd also be frozen stiff, especially in mid-Wales. The VPM M16 or whatever it's called is open cockpit with your head above the windscreen, and at 70 kts that is coooollllddd. Definitely try before you buy. I'm pretty sure that weight is not a problem though.
