I had a game the other night against a newer player. He had tycho with ptl, daredevil, and experimental interface.
During one round, he focused, then did a daredevil with experimental interface that landed him on a debris, he then did ptl to boost off it.
He thought it was legal because of tycho not being effected by the debris stress, but I thought it wasn't because regardless of stress, you can't take an action when on an obstacle.
Or does PTL get around that somehow? I do know that someone can give you a free action while on a obstacle, and you can barrel or boost off it if the template doesn't touch the obstacle at all, so maybe it's the same idea?
It didn't have a big effect on the game either way so I let him keep the boost.
