noob your idea is totally possible. I cant recall what video who/how/when, but with the correct timing and the right lock you can get the one foot stuck off the board before the character has time to finish the rail/ledge

I think it might of also had to do something with holding the right bumper, could be wrong. iunno that rb button in s3 did a lot of glitchy awesomeness lol

im sure you can figure it out.

I always remember trying to do this in s2; one foot tailslide nosegrab. Trying to pull for a nosegrab with the foot off. I'd always get sent flying into the air or into the ledge glitching hahaha.
