Correct me if I'm wrong,.. when flat basing for say, "X" distance (longer than a few dozen yards?) on a packed or icy run, particularly /w a cambered board. ANY small lapse in technique, i.e. shoulder alignment, centered/forward weighted stance etc. is likely to give you that "Edgy" feeling? Is this correct?
I have noticed myself, when riding straight & flat (...trying to get comfortable with speed,) my cambered Arbor Roundhouse will get a little,.. "fishtaily" for lack of a better/proper term! The rear of the board will tend to slide/turn down/across slope one way or 'tuther!
I assumed it was due to getting sloppy with my shoulder alignment?
