Back on topic..... For those of you familiar with both the charlton volcano and the Legacy spine, Legacy is the natural step up from charlton volc. If you've got yourself over the charlton volc, then my advice would be to go directly to Legacy and throw yourself over that spine before you think about it too much. There really aint much difference - a little more opposite carve at Legacy and you'll be fine.
where in the list do you reckon the rom volcano fits. that thing scares the life out of me!
Bigger volcanos are harder to ride as it happens, as you need to travel forwards a wee bit more than on a spine, which is harder on bigger stuff. Lots of front wheel hangs to be had on big volcanos....
The trick at Romford is to ride slowish and carve a lot, that way you'll probably be able to monster truck through a hang up a few times until you have it dialled. And as it almost always the case, you need to get your head in......
Alternatively, launch it to flat ground just to get it over with, then shrink it down as you get more comfortable
As for the list, I'd say charlton volcano, legacy spine, charlton spine then Rom volcano. If you learnt it all in that order then your technique would be pretty good, and you wouldn't be so freaked out at Romford.
Roms volcano isn't that much fun really, the spacing is a bit odd between that and the obstacles at the ends, and having two different ramps at the ends doesn't help with the flow at all. It's good that its not conventional, but a pain in the arse to learn and get smooth on. I barely ever ride the thing.
