Hi fellas, just as the title says really, what’s the difference between the two seat boxes? Is it just one has 36mm legs and the other has 30mm legs? Or are there other differences as well, I’ve had a full day on my mates z36 at woodlands thirsk last September, and I absolutely loved it, very very sturdy and surprisingly light, will the 36mm legs make a big difference over the 30mm legs, I’ve never had a go of a z30, and the z30 is a little cheaper or should I just pay a little extra and go for the z36, many thanks for time.
