I take travel powers for concept. Always.
For some characters, I wish I could not take one and still get around - temp jetpacks are the closest I usually manage - or could get a motorcycle, etc. A lot of them would be well-served by being able to recolor the FX on Prestige Slide and combining it with SS and/or SJ to get ice or earth ramps for my controllers, etc.
I tried Flight + Afterburner, but two aspects of the latter power were a dealbreaker for me: it doesn't automatically detoggle when Flight (or Hover) does, and there's currently no Minimal (i.e., zero) FX option for it. So there I was, getting the "whoosh" FX around me while I was on the ground, just walking. That just looked/felt stupid, so I respec'd out of it and haven't taken it again since.
