My targas are great, but one minor complaint about highbacks. Say your back foot is ducked and you rotate the back foot highback to be parallel with the board edge, there is this nub on the bottom of the high back that now pokes out into your boot, created by moving the screw that mounts the high back from position 1 to position 2. Although you totally can't feel this nub and doesn't affect riding, it does after days of use start to wear a hole into you boots where it contacts them. I think I'll take a grinder to it soon.
edit: i have the 06/07 targas, not sure if this happens on the 07/08
