I have landed the odd one clean, but I don't practice them nearly enough to have them dialed and they are usually pretty ugly looking when and if I do land them. I wouldn't go and say "I can barspin". It's more of a "I can bar spin...from time to time" kind of thing.
You saw the day I tried them at Hay Lakes, which is what I assume you're referring to, and was also a disaster.
The only place I've actually landed them clean(ish) is out of the big bank at Kask. I've landed them before, but to be honest, it's just such a frustrating trick I've over all given up on it.
They're little tricky to learn. A lot of commitment is needed. I have a habit of taking my right foot of if im going to bail it for some stupid reason.
