Tempting... Although, meh.. TL01 is monocoque, not a tub

As for your belt driven carbon fibre car Martin... No tub there either.
Will have to carefully consider this, I am finding my Mardave rather enjoyable.
PS: Right not I am tempted to say "YOLO! I'm doing it!". But I reserve my right to change my mind without prior warning or consideration for anyone's feelings.
