SVA: Roadster or Ron Champion

[rustymini]

If both the Haynes Roadster and the Ron Champion Locost where both built exactly as per the books, which would be the easiest to get through the SVA (or the new IVA)?

I did build the Ron Champion chassis as a college project in 1997 (long ago broken up by the college for the tube) and have decided to have another go. I have both books but haven't decided which way to go yet. Also I must admit I find the idea of the SVA or IVA a bit scary.
