I still fail to see the "bucket loads" of airtime on the Nash. Sure, there is some - but it's hardly as profound as many other rollercoasters (and woodies!). Also, it is not intense. Joris en de Draak, Troy, Tonnerre de Zeus and Gwazi are all more intense (apart from the double dip) I would argue! I really haven't a clue where this overrated view of the Nash comes from. OK - it's old - and I do like it - so credit for that, but still... I have been on 4 better Wooden coasters!
Having only been on Joris on that list, I'd say that the Nash has a lot more airtime! Of course airtime isn't an opinion, it's a measurable fact, so one must more airtime but it's a matter of debate of which it is. We'll have to wait for someone to do a scientific study on it. :P
The double down after the station fly-over was the only moment on Joris I felt a huge amount of airtime on that ride. Don't get me wrong, I love it, but I think the Nash is better. Think of the airtime the Nash has on its MENTAL first double-drop, then on the "Valentines" hill, then on the second double drop...
Interestingly, it seems the modern trend for double coasters is to have them dueling like Joris. That's great, but it means for a lot of the layout you're not next to the other train. I prefer the Nash style of just having the two tracks run side-by-side throughout the ride, so (if it was bloody run properly) the trains have that interaction all the way through. :)
