I've always rigged tail down like the plastic at the top of the picture.
But I've recently started mucking around with tail up.
And I dont know if its just me - but I reckon tail up might be a much more unstable presentation on the drop. I swear my tail up presentations are much more likely to spiral on the drop with slack line.
I havent done alot of testing and there could be other factors at play - (such as my dodgy rigging
) but has anyone else experienced this?
