Contrarily to the general trend, I think the teleport thing is a bad idea. 0.05% may seem small but when used frequently enough it's just a question of 'when' and not 'if'. And there isn't really anything you can do about it, besides the obvious: not using the teleport which would be lame beyond words.
With the flying thing on the other hand, there's definantly some wiggleroom to make it work. For instance, you could make some kind of custom parachute that is just big enough to slow you down to a reasonable landing speed when popped.
EDIT: after posting it occured to me the whole parachute thing isn't so different from how a wingsuit flyer lands. So I googled a little and guess what... The average speed of a wingsuit is 100mph! What more proof could you possibly want that the flying thing is perfectly viable?
