farkin winge!
i tried the 9 on saturday and so did a lot of others.
was rigged up in 5th line mode and worked fine. in fact better than fine, was pretty dam nice. considering it was pretty light and was draggin my tail around was gruntier than i thort.
i have seen ry, jake and others riding it on 4 lines and they didnt seem to have quams...
maybe listen less to the forum stirrers and try blaming your workmanship rather than your tools.
one thing i found was there are a lot of settings and adjustments with knots and so forth so maybe you guys just dont spend the time setting your gear up properly.
if you are over em, ill have em!

or sell em and go to another sle, who knows you may find the grass is greener, or you may find all sle's require a bit of change in your riding style to suit...
